Right, so I bought the Amazon retail version of ArmA2 and ArmA2:OA==>ArmA2:COps Installed em into the same directory (/Program files/ArmA 2/) and added the @DayZ folder as normal to that directory. Run arma2oa.exe with the -mod option and enable arma2 and dayz in the expansions menu screen. But then I get: "You cannot play/edit this mission; it is dependent on downloadable content that has been deleted.dayz_code etc." whenever I try to join a server. Halp :>
