If you get an error message while using a program I have found it really useful to copy the error message word-for-word into the clipboard, then paste the error message into Google. You might be surprised to find out how many people have had to deal with the exact error and have solved the problem.

It's amazing how many seemingly esoteric topics have been indexed by Google. There are of course other search engines that do a good job of locating information about software error messages, but Google is my personal favorite.
