There are a few tabs at the top of the Steam client, one of them is "Library." Click it, and a drop-down menu will appear. "Games" is the first item on the menu. If you have any existing games in Steam, it will all be listed on the left panel. On the bottom left-hand corner of the app, click "Add a Games" and select "Activate a Product on Steam" from the menu that appears. A dialog box that will guide you through the process of adding your AoE2HD product code. The dialog box will prompt you to enter your game's product code. This code is provided to the buyer when purchasing the game and will usually be found on the retail CD/DVD case that came with the game. The code is not of specific length and can contain both alphabets and numbers. Enter the code into the fields and follow the onscreen instructions to complete the process. Note that, because using the code to install the game on your computer and adding the game to Steam are two separate things, it is still possible to use the code on Steam after you've already used it to install the game on your computer.

Summary: Access the Steam Game Library. Select "Games" from the drop-down menu that appears. Add your AoE2HD product code to Steam.

Creatinine is a waste product produced by the body when creatine, a metabolism substance that helps convert food into energy, breaks down. Usually, your kidneys help filter creatinine out of the blood. The waste product is then passed out of the body via urine. High creatinine levels can indicate a problem with your kidneys. High creatinine levels can be the result of regularly consuming a high amount of protein or partaking in strenuous exercise. Creatine supplements may also increase levels of creatinine in blood and urine. A creatinine test measures how much creatinine is in your blood. Your doctor may also perform a creatinine clearance test, which measures the amount of creatinine in your urine. The amount in your blood should be low, and the amount in your urine should be high. These tests only provide a "snapshot" of your kidney health. They only measure the amount of creatinine in your blood and urine from one-time samples taken within the past 24 hours. The normal range for creatinine levels will vary based on whether you are an adult male, adult female, teenager, or child. The value you should be at may vary further based on your age and body size, but there are general ranges you should shoot for. Normal blood creatinine levels are: Men: 0.6 to 1.2 mg/dL; 53 to 106 mcmol/L Women: 0.5 to 1.1 mg/dL; 44 to 97 mcmol/L Teenagers: 0.5 to 1.0 mg/dL Children: 0.3 to 0.7 mg/dL Normal urine creatinine levels are: Men: 107 to 139 mL/min; 1.8 to 2.3 mL/sec Women: 87 to 107 mL/min; 1.5 to 1.8 mL/sec Anyone above the age of 40: levels should drop by 6.5 mL/min for every additional 10 years of age There are several different reasons why you might have increased creatinine levels; some of these conditions are more severe than others, but all mean that you need to take steps to get your creatinine levels back to normal. Renal failure or impairment: If your kidneys are damaged, they cannot filter creatinine out of your body through glomerular filtration as they are supposed to. Glomerular filtration is the outflow of filtered fluid passing through your kidney. Muscle destruction: If you have a condition that causes the breakdown of your muscles, the broken down muscle tissue can get into your bloodstream and impair your kidneys. High intake of meat: Eating a diet rich in cooked meat can increase the amount of creatinine in your body. Hypothyroidism: Having a dysfunction in your thyroid gland can have an influence on your kidney function. Hypothyroidism can decrease your kidneys' ability to properly filter waste out of your body.

Summary: Know what creatinine is. Understand how the test works. Interpret your results. Understand why increased creatinine levels occur.

Before you get down and dirty with your hardware and computer settings, check to see what kind of speeds you are getting and compare that to the advertised speeds for your service. There are a variety of speed test sites on the net, just search for "speed test" in Google and pick the top few results. Different tests will give you different results. Even the same test may give you different results between tests. This is due to the location of test servers and the number of people sharing your connection. Take multiple tests and find the average speed you are getting. You may need to have Flash installed to run the test. If given the option, pick the test server closest to your physical location. This will help get you the most accurate results (on speedtest.net, this is chosen automatically based on ping) Check with your service provider to see what speeds you should be getting. Keep in mind that speeds advertised by your provider are "best case" speeds, and you may not be able to actually get that number on a regular basis, especially if using WiFi. If you haven't upgraded your internet in a long time, you may be able to get better speeds for less money. Companies aren't usually keen to inform you of better deals, so check to see if new services are available that weren't when you signed up. Check with all the providers in your area. Be aware of the megabyte/megabit difference. Some Internet Service Providers (ISPs) advertise in megabits, not megabytes. There are 8 megabits (Mb) in a megabyte (MB), so if you are paying for 25 megabits per second (Mbps), then that's just over 3 megabytes per second (MBps) of actual maximum transfer speed. If your test result was measured in Kbps, then you divide that number by 1000 to attain your measurement in Mbps. Restarting your modem and router can help alleviate some network issues by cleaning up old data and re-provisioning your modem configuration from your internet service provider. If necessary, your modem will automatically download firmware updates from the ISP. See this guide for details on resetting your network. If you are using a wireless router, some devices can affect your connection due to interference. Wireless routers come in multiple varieties; 802.11 b, g, and n (2.4 GHz) or 802.11 a (5.8 GHz). Common devices that can interfere with your wireless connection are microwaves and cell phones, many of which operate in the 2.4 GHz range. In order to minimize interference, turn off data on your phone and move your microwave oven away from wireless devices and your router when you're using the connection. Sometimes you just have a bad connection that can only be fixed on your provider's end. They can usually tell if your connection is substandard without having a technician come to your home by reading signal levels off of your modem. If necessary, they will send a line technician out to your house or neighborhood to check their infrastructure. If the problem is on your end, you might be charged a fee for the visit, so it's important to try troubleshooting over the phone or internet first. If you are connected to the internet via a Wi-Fi router, poor signal can lead to lower speeds and dropped connections. Move your router closer to your computer if possible, or move the computer so that it is closer to the router or keep the router on top of a cupboard to transmit better signal. Clean out the dust from your router and modem once in a while using a can of compressed air. This will help keep the unit from overheating and consequently, improve its stability. Maintain proper ventilation around all electrical components to avoid overheating. When you activated DSL, you hooked the line from your phone jack into one side of a rectangular box filter. On the other side, you have 2 lines coming out, 1 for your phone and 1 for your modem. If you are using a DSL connection over your land-line, make sure that you have high-quality filters in place to get optimum signal speed. If you are using satellite internet, your internet connection might be altered because of wind, heavy snow, rain, lightning, static, or other electrical interference.
Summary: Run a speed test. Compare your results against what you're paying for. Reset your modem. Check for sources of interference. Call your internet service provider. Relocate your wireless router or computer. Check your filters if you have DSL. Check the weather.
