I play the game for about 45 to 1 hour on multiplayer and it jus closes itself. no errors , no dump, nothing! If i run it through hamachi wiht my friends (tricks it into thinking were lan) it will go to 3 hours exactly then close. Anyone have any advice?

Im getting this crash every 45-50 min on the T. The games just closes itself. Any game i play online does this. But normal games on my PC does not.
