Recently my Arma 2 and Arma 2:OA started bugging out so I uninstalled both, deleted mods, etc. Now, whenever I try to join a server, vanilla, ACE, DayZ, etc. I get kicked instantly. I've tried running Steam as administrator, running Arma 2 OA.exe as administrator, reinstalling BattleEye, and verifying the game cache multiple times with no luck. If you need any more info, just ask.
