Do understand that learning a computer takes both trying and quitting . Try what you can think of and if you success is elusive, leave the computer alone. Accept downtime as a necessary part of problem solving. You are likely to have new Ideas. Or you may not, but at least you will not have high blood pressure or throw the computer through a window.
Computers are time-sinks.
Understand and plan how to invest that time enjoyably or profitably. When you are convinced the problem is the computer's fault - it usually isn't. A friend says that computers are like a neurotic lover. If you don't say exactly the right thing to them, they freeze up. I have been trying for years to identify a random error by a computer.
