I just finished installing Arma 2 combined OPs off of steam, and now I can't open it. When I try to open it the loading bar stops at the last check mark and an error message pops up, something about the wrong addon for DirectX I think. I don't know how to fix it, has anyone else had this problem? ---------- Post added at 13:21 ---------- Previous post was at 13:20 ---------- Here's the error message

Thank you Placebo, that was the problem
