i'm having the exact problem. i've got the 2 disc GOTY edition, and i get lucky sometimes where it goes long enough without freezing but freezes up again later. i keep opening task manager and it says the game is not responding so i end task. everytime i reopen it i save almost every minute so i can keep going past the freezing problem, but it makes the game damn near unplayable. i've been looking desperately for a similar claim or problem, i thought i was the only one!
