I have the retail version of Arma 2 combined operations and I have the Dayz Commander.Whenever I try to join a server it says there is an error launching Arma with Dayz. I know when people have Arma 2 CO they log on on steam as administrator or something like that but what do you do when you have Arma 2 CO as the retail version?When I do this stuff with should I uninstall my retail version and install my steam version
