I seem to be struggling with these two steps. I've had arma2 / OA on my computer and playing DayZ for a while. In the past day or two my wife logged in with her steam account and purchased the arma2/OA combo that steam is selling. Steam didn't download anything new since it was already on my machine and when she launched DayZ she was using my profiles. So I removed OA from steam and redownloaded/installed it with her account. Still no luck. Ideas?
