If you mean which version of ArmA 2:OA I'm running the latest patch, the beta which was needed for one of the launchers to work properly. I have tried Six-Updater, Spirited Machine's launcher, the DayZ updater and some more launchers. EDIT: Okay, so I downloaded and installed the mod with Six-Updater, even though it is extremely slow from time to time. It seems to find the right files and games, as it says I'm running ArmA 2:OA (CO). But when I try to join servers it says all the files in my /Expansions/beta/Addons folder aren't accepted by this server. When I try to delete them (Except /Expansions/beta/Dta/core.pbo, which will make the game krasch if gone) it just says that: - I cant edit/play the selected mission, because some file is missing, - Or that the file core.pbo isn't accepted. - I simply get kicked, or can't connect to the host.

Why hello there, When I first saw this amazing mod I knew that I just had to play it, so I went and downloaded ArmA 2 Free and bought ArmA 2:OA (SHould've bought CO over Steam though...) and then went on trying to get the mod working. Here's what happened: I first tried using this guide: http://goo.gl/cVB4h, which did not work because Six-Updater wouldn't find my arma2.exe and so on. I later got it to work better, but still couldn't join any servers. I then tried some other guides which included some other launchers, but I keep getting "Connection Failed", "Files not signed by a key accepted by this server" or "You can not edit/play this mission...". I've had so many different problems, so I just purged all evidence of Arma 2 off my computer and tried installing everything again, but instead following this guide: http://goo.gl/667q0. I followed every step and did everything it said, but still the mod won't work. I also suspect that I have some older version interface when connecting to servers. Well, any ideas about how I should solve at least one of these problems? I'll can give you more info about the problems and such if you need it. / ramenfeed
