Airo101 10 Posted January 22, 2015 So I recently reinstalled my copy of ARMA 2 OA and found out that if I try to launch it from steam nothing happens. ARMA 2 works fine. If I try to launch it from game's folder, I get 0xc000009a eror. If I however press enter multiple times while ArmA2OA_BE.exe, the game launches at some point. However I still can't connect to any server, as I either get thrown back at the server browser, or get "Failed to update Battleye" error, or the game closes and tries to update Battleye in a cmd window, only to fail. Things I tried so far: -Completely reinstall both games multiple time from different steam accounts. -Verify integrity of the cash (It shows that there are two files wrong every time) -Delete all mentions of Battleye from pc. -Download last Battleye .dll from their website. Nothing helped me so far. Share this post Link to post Share on other sites
