Okay! This Steam thing has me really miffed right now. I have tried everything since whatever patch was put out and I am getting nowhere. Combined ops was working fine for me before this. I have gone as far as totally uninstalling OA and re-downloading it. I have verified, ran arma 2 first then OA then tried combined ops. Nothing is working and before I uninstall both ArmA's (which is probably the answer) do any of you have a suggestion on what I can do? I just get a DOS window that comes on for a split second and disappears and I have no idea what it says.
