There is supposed to be a picture let me type it out I gues This is the error Go to steamapps common arma 2 operation arrowhead @dayz addons community_crossbow.pbo And there are several more files then it says these files are not signed by a key accepted by this server. To play on this server please remove these files or install additional files This happens on every server

I get this error every time I connect to a multiplayer server And when I do delete these files and try again it says I cannot play with the files I deleted The only thing I can think of is that I did not download the combined version of arms I got arma 2 and arma 2 operation arrowhead and the beta separately and then I have the mod from steam and I really want it fixed Help thx Caffeine
