I shut down my server since this problem is solved, because i don't want to lose my Arma II + Arma II OA Key from the server because of this glitch. I would recommend that all server admins make this too so no user/server lose their keys because of an global ban. Battleeye said we should not have fear and they unban us but if you see on the last problem it takes long that they unban innocent players. We don't know if server also vulnerable but if you have your own Serial Numbers on your server as i have you should really shut down it to minimize the problem.
