I dont know which level i am playing, but i have played for 11 hours since it came out and i am stuck at a level where i often get killed (compaign), when it happens i press enter and the game normally starts again after a few sec, but not at this level, it won't loade, when i again press enter again or esc, it shots down the game and i have to start the game all over again (luckily i have an ssd or it would be a pain in the ...)

I have an i7 870 3.52ghz,120 gb kingston ssd, msi gtx 660 oc, 8gb ram , seasonic 620 80+ psu

(havn't tried rebooting to see if that would help)
