When ever I play Arma 2 and Arma 2 OA they both shut down mid game even if I don't start up DayZ. When I play DayZ, the background screen when i join server is blue, there is a giant blue blob covering the DA and half of the Y after I join server. Then i click ok to join( Next to the disconnect button) and it shuts down saying Arma 2 OA has to quit. Help? I have not tried reinstalling Arma 2 and Arma 2 OA. Maybe I should try that...
