I have an I7 2600k standard clock, Asus P8P67 PRO REV 3.1 mb latest BIOS, 16 gig corsair Vengeance, KFA2 680 GTX, 1tb Samsung F3 hdd. Windows 8 PRO

The beta would crash to desktop when 99% loaded in multiplayer and now the full game does as well. Wtf is going on? Fresh install of windows 8 and no fire wall etc. Campaign plays absolutely fine.
