I did this, it then came up (when I tried to join a server) with some sort of .pbo files such as air.pbo and air2.pbo which I needed to get rid of. I have now deleted all these files that it told me to and I'm back to what this topic is trying to help with (.chernarus/ca_dubbing) I have arma 2 non-steam and OA steam version, does that change anything?
