It just quits, no blue screen, no error message. When I reboot the windows doesn't even notice that it didnt shut down properly. I had the game installed before with no problems. Then I won and uninstalled it then recently reinstalled it. My boyfriend recently bought a new computer because he was having this same problem and tried all sorts of stuff but wasnt able to make it go away. I have seen alot of posts about installation or not being able to play, but I have not seen any questions about this problem.
