I just uninstalled arma 2 free and cannot get it back!

so foolishly i just UN installed the free version of arma 2 and now i cannot get it back... the reason why i uninstalled is because my game was not working at all due to me messing about with the new update so i decided to uninstall both my OA and Arma 2.

i have purchased OA but now do i need to purchase ARMA 2 aswell?

damn my luck!

The wiki is your friend but I'll just point you to where it points.

Not sure if your copy is the Steam version or not. The Arma 2 "demo" is the free version on Steam.

thanks for the link bro... just installing arma 2 free again, since i got OA from steam and arma 2 from a different site would this affect me when downloading Dayz again? or do i need both OA and arma 2 from steam?
