Okay, I am not really savvy with computers, so I need a "How to fix for dummies" type of answer, if possible...
I bought this game called Temple of Elemental Evil (Dungeons & Dragons) and it loaded properly. When it finished loading, I was given a choice to launch the program immediately. And I was able to play it with no problems. But then after I closed the program, I could not open it up again. "ToEE.exe has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."
I uninstalled it and reinstalled it, and once again I was able to play if once, but could not re-start the game after closing it.
