I've got the exact same problem Choke. The game just randomly freezes when playing. Sometimes it just closes so that I'm sent back to desktop, but the game has stopped running. Other times it just freezes and there's no way out. I never get a black screen or something. Just froze. I heard it could have something to do with cpu temperature? That would be questionable because other programs work fine after i've been sent back to desktop.
I've got a PII400
128 Mb RAM
6 gig of free disk space
Diamond Viper V550
Please help,
