When i start up my game and play for about 6 minutes
 
	first time i get a crash saying "the system detected an overrun of a stack-based buff in this application this overrun could potentially allow a malicious user to gain control of this application." 
 
	after a few tries i get no msg at all, no reason, nothing..
 
	i've tried everything i could do, (reinstalling the game, rebooting, repairing, system scan.)
 
	you name it, so it would be great if somebody could help, Thanks.
