I started playing the Operation Arrowhead campaign earlier and the first thing that happened was "Invalid crew US_Soldier_Pilot_EP1 in A10_US_EP1" came up. I just clicked continue and the news scene carried on normally without problems.
However in Backstab the Takistani(I think) soldiers didn't load, neither did the tanks. (I watched cutscene on youtube after to see if there was something wrong because it didn't look right). Audio seemed fine. When the part when you shoot the commander came up, my scope was looking into the air and again, the soldiers and car hadn't loaded.
Mission 2 would not load at all. The loading bar finished but it did not go into game.
I'd appreciate any help, I really want to play this game after finishing Arma 2 yesterday.
