Ok, before I start I want to let you guys know that I realize there is a million other posts exactly like this, but I'm sick of searching. I have tried everything like running steam as admin, deleting both games and reinstalling them, exiting out of steam then back in, restarting my computer, and more. Arma 2 seems to work its just OA. In regedit in the Behemia Interactive NOT Behemia Interactive Studio it says in the Arma 2 AND Arma 2 OA Folders the only thing it has is (Default) No key, data, or main. Just (Default)
Please help
