[/color]I've clicked on "Verify Integrity of Game Cache" if that's what you're talking about but I got a response saying "1 files failed to verify and will be reacquired."

I've checked it off and it still hasn't worked. And Neuro, c:\programs files\Steam\steamapps\common\arma 2 is not in my files. ---------- Post added at 20:33 ---------- Previous post was at 19:12 ---------- It seems my OA files are corrupted. How do I cleanse them?

When you say properties you mean going to the library, rightclicking and press properties?

None of these things have worked, the errors still show when I load it from Steam AND windows.

I don't know what that is or how to check...

I've tried this and it doesn't work for me. Even when I run it as Administrator it still shows the errors
