Hi all; just joined the forum so forgive me if this is the wrong place to post or if this has been posted before. I bought Arma 2 and Operation Arrowhead the other day on steam along with BAF and the PMC add-on. Arma 2 and Operation arrowhead works fine but the other two don't. When I load the game from OA I get various error messages. When I proceed to the campaign all the Arma 2 and OA are there however the BAF one isn't. The PMC campaign is there, but when I try loading it it doesn't work (I can't move at all and only zoom with the scope and change between third and first person). I then went to the editor and had a look at the PMC and BAF units and they all have terrible textures as if it were the lite version. When I had a look at the expansions part of the main menu it said that the PMC and BAF expansions were the lite versions despite the fact that I paid for and downloaded the full versions. When I had a look at the BAF installer it said the game files were corrupted. So I tried re-installing the games and expansions a couple of times and that didn't work and now I have no idea what to do other than hammer at my PC furiously. Any help would be really appreciated.
