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.
