Arma 2 OA is being glitchy (Sorry for lack of better explaining)

[bathtubbarracuda 7]

So I've reinstalled Arma 2 and Arma 2 OA three times prior to this. I'd also like to apologize if this issue has been resolved previously, and I'm sure it has, and I haven't looked.

 

When I launch Arma 2, it's all good.

 

When I launch Arma 2 Operation Arrowhead, I'm greeted with this message:

"No entry 'bin/config.bin/CfgInGameUI/MPTable.shadow.' "

 

After I launch it, this message pops up:

"Error compiling pixel shader PSSpecularAlpha:0"

 

When I click "Ok," the game closes.

 

Any suggestions? Thanks!
