VoDeN (DayZ)

I tried deleting all Arma 2 & AO local files and other files, reinstalled one by one, launched in adminstrator from steam, then launched the withSix and installed DayZ via there, and still having same problems as before. The expansions menu says all expansions are activated from ArmA2 >.<

Starts off with launching DayZ through PlaywithSix and I get the ArmA 2 OA error; "Failed to load file "E:\Steam\Steamapps\common\ArmA 2 Operation Arrowhead\pmc\addons\air_pmc,pbo" - decryption of headers failed. The game continues to load though, and I get the error - No entry 'bin\config.bin/CfgVehicles/Soldier_Crew_PMC.scope'. When trying to join a server I get; You cannot play/edit this mission; it is dependent on downloadable content that has been deleted.cacharacters_pmc Been googling to try and resolve this but haven't found a fix yet, anyone able to help? xD
