I have a problem, when Harry gets to the forbidden forest in his second year,(following the spiders) the game crashes, I ran system requirement lab and it said my computer was fine to run the game, I have windows 7 my game is compatible with windows 7.
I've been able to play through the game completely on Windows 7 multiple times. Your saved-game might be corrupted, so starting over with a new save might work. If you really can't get past that spot, I have a completed saved game for Windows that you can download. You'll need to follow the directions carefully, and maybe get some help locally if it's a bit confusing. The ZIP file is located near the bottom of the thread (the one linked at the top is no longer available).
