Hello, I have been playing Dayz for a pretty long time - no problems what so ever. Now this morning when i'm trying to launch via Dayzcommander i says "It doesn't appear you have Arma2 OA installed, etc.etc" (check jpgs) Aswell in steam the "arma2" icon has dissapeared and when i try to launch OA it says bad serial (check jpgs) Would appreciate a little help. Thnks in advance
