I followed a video on youtube, apparently I just need to reinstall ArmA II which is what I'm doing now, at 35% so far at 6.8mb/s so I'll let you guys know what happens when it's done. I heard it's just some file corruption or something, should fix it I guess. I was being pretty dumb, I was running ArmA II: OA instead of Combined Op which was causing it to error the chernarus thing sinceeee it wasn't checking the original ArmA II files I guess.
