FirePanda 1 Posted August 11, 2012 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 Share this post Link to post Share on other sites
Placebo 31 Posted August 11, 2012 That sounds like a corrupt download. Exit steam, reboot, disable any antivirus, launch steam as admin http://img717.imageshack.us/img717/5892/steamadmin2.jpg then right click operation arrowhead in the library and go to properties/verify cache integrity.
