I tried playing call of duty world at war, and when I try booting it up, it then crashes back to windows and an error message pops up saying "call of duty world at war has stopped working, please choose to end this application now."

I've tried reinstalling it, and this same problem persists. I clearly remember playing this game a few months ago on this same computer. What the hell is the problem? The patches are like 2GB's each and you have to download them in sequence and install them in chronological order from oldest to latest. And there are like five or six patches.

Does this game have compatibility problems with Windows 7?

Oh god, why can't I run this game?..............
