So i was able to play Dayz before then i had to change something to it. I dont remember what it was but after that i cant get on. So i reinstalled Arma2OA then dayz on steam. I have the DayZbeta launcher and ill double click it and it will pop up real fast and go away. I dont know what is happening. If i go through steam to launch Dayz from the beta it says failed to start game(missing executable) Please help if you can!
