Hey,

I have DayZ on Steam (Buyed/Original Version) so i was able to join my Server.
EDIT:
This is what BE says in console after pup up the Error "Unable to locate a running instance of steam"
10:31:43: Starting BattlEye Service...
10:31:45: Launching game...
10:31:48: Note: File blocks can be ignored if they don't cause problems with the game.
10:31:48: [INFO] Blocked loading of file: "D:\DayZClient\DayZ\SmartSteamEmu\SmartSteamEmu64.dll".
Just found OLD solution for this Problem....
