A typo error in either the password or the name. Invisible characters, such as spaces, can cause errors in the password or the name. We think your problem can be solved by using one of the solutions above. We try every password ourselves before sending them to you, in order to make sure that they work. If you still cannot get the game to work after trying the above, it means either the game file or the options file is corrupted.
File corruption can happen during downloads or when the computer crashes.
Then restart the game and try your password. If that did not work, it means there is a problem with the game file and you should download the program again. It is highly unlikely that you will reach this point, though. All rights reserved.
