Same here. If start the game from dayz.exe it works, but the moment i try to connect to servers it tries to start Battleye and it crashes, so I assume its Battleye related problem. The thing is as fellow users listed before I didnt change a thing on my system. DayZ Devs point to Battleye support, the Battleye support points uselses measures on their support page. With all due respect dear DAYZ DEVS, I didnt touch a thing, and after the last update Im unable to even start it. I perfectly understand that its alfa, but thats not the tipical case of crying out loud for bullsh*t. Mabe its time to abandon that ridiculous Battleye junk, famous for causing a lot of problems with Arma as well.
