Nothing works anymore after reinstalling

[magicool 115]

Hey I moved Steam to an other partition because the oirignal was nearly full

so I deleted all games and I downloaded and installed Arma2:CO via steam again

now I aint able to start DayZ via the "_runA2CO_beta" file like I always did

only working way to start it is via the "Launch Arma2 OA Beta Patch" link

but after the the little window with the tiny tick markers loaded this messages appears:

the game starts "normaly" when pressing ok but as soon as I'm in the main menu this message appears:

When I try to join a server it says "You can not play/edit this mission; it is dependent on downloadable content that has been deleted.chernarus"
