When playing mid-game, about halfway through, during a medium-sized battle, my game will crash to the desktop, saying windows is searching for a solution. I don't keep my XP or anything, there is no record of the game happening. Have you guys experienced similar issues? Know any fixes? At first I thought it was Windows 7, but I've played with two of my brothers with Windows 7 and neither of them have crashed. I think it's my video card(Radeon 5870), but I'm not sure.
