ArmA2: OA Error upon startup

[N00bLeader91 0]

Hello. I just installed ArmA2: OA and when I go to launch the game, this error message keeps coming up, and a couple seconds later another windows pops up saying "error compiling pixel shader PSSpecularAlpha:0".

No, I have not installed the DayZ files yet, and Yes, I have tried validating the files, which steam has told me each time that I validated it that 1 file was missing and will be replaced, however, it is apparent the file is not being replaced. Please help!

P.S. Regular ArmA 2 works just fine, only OA is giving me grief.

? Try Reinstall first then see if problem happens again.

I have the same problem. I deleted local content and re installed, but the problem persists. It's only since the recent beta patch that I've had this problem.
