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 ArmA2:CO through the shortcut provided and see @DayZ on the right-hand-side of the menu screen.
Select an MP DayZ server, connect and then I get disconnected, error msg: "You cannot play/edit this mission; it is dependent on downloadable content that has been deleted.dayz_code etc."
Halp :> Am I supposed to put the @DayZ mod files folder somewhere else?
