Hi, I actually tried all solutions suggested after lot of tries I actually have deleted the arma 2 OA folders in registrery and verified steam game cache added the "-beta=Expansion\beta;Expansion\beta\Expansion -mod=@dayz -nosplash" line to the launch options in the steam OA shortcut. have copied the key entry from ArmA 2 to the one of ArmA 2 OA (the key entry was visible but with no code inside) Finally (since I was still unable to join servers) I deletted the @DayZ folder in arma 2 OA steam installation folder and I installed DayZ commander to reinstall the mod Launching the game with DayZ commander is actually working. I didn't try yet to change others things (like the shortcut options in steam) but I'lm quite sure my solution was either the copy of the cdkey value in regitrery and/or the use of DayZ commander. I hope it wil help some of you
