"Bad serial code given during setup"

Is what i get when i try to launch arma2, i can launch operation arrowhead, but not Arma2.

Oh and if i dont buy the joint operations off steam & just bought the both above alone, will ill still be able to download DayZ?

start both arma 2 and operation arrow head before anything, that should fix ur problem :)

^^ launch normal arma 2 and get to the main menu, close it down

^^ launch arma 2 OA and get to the main menu, close it down

^^ use any launcher you like or just launch OA again click expansions and enable @DayZ and dayz

^^ dont forget the arma 2 beta patch
