So got Arma 2 and Arma 2: OA on Steam a while back. I loved the games and had no issues with them. Yesterday a patch was rolled out for it, I found out while waiting for the DLC that Arma 2:OA and CO will no longer start up at all. I've tried reinstalling, system restore, starting Steam as Admin, revalidation the files and downloading new drivers. I just got BAF hoping it would fix it but BAF is having the same hang ups. It starts to load up saying Setup step 1 and then nothing happens. Oddly vanilla old Arma 2 is working fine. Can someone help me out:?
I'm running an ATI 4850 on Windows 7 64 bit with quad-core with 6 gigs of ram.
