You need to: 1. Uninstall arma 2 and OA 2. Reinstall Both games 3. Run both of them (not at the same time) 4. Patch for 1.60 then 1.62 then run the newest beta patch 5. Hopefully it works, it worked for my friend

Hey Man I had this problem today and I uninstalled my game and reinstalled and found out I was downloading OA into my arma 2 directory (C:\Program Files\Bohemia Interactive\ArmA 2) and that was the wrong thing to do so move it back one to bohemia interactive and it should fix your problem :)
