Hey everyone, after about 4 months I've decided to play DayZ again, although there was a problem I encountered when starting up DayZ via "Play WithSix" launcher. After selecting a server, the DayZ screen loads. Following the screen is the "Waiting for Host" screen, and the following prompt shows up. Files "C:\Users\-----\Documents\arma 2\@3lb_f22\addons\3lb_f22.pbo", "C:\Users\-----\Documents\arma 2\@GLT_MissileBox\addons\glt_missilebox.pbo", "C:\Users\-----\Documents\arma 2\@GLT_MissileBox\addons\glt_missilebox_config.pbo" are not signed by a key accepted by this server. To play on this server, remove listed files or install additional accepted keys. After deleting @GLT_MIssileBox and @3lb_f22 folders, Six Launcher updated and re-installed both of these folders. So, I concluded that removing them was not an option. (Although I may not be doing it correctly of course). I have gone into Arma 2 Operation Arrowhead and checked ON both of these extensions (GLT Missile box and 3lb_f22). I appreciate any assistance that is given to this thread, if this SAME exact problem is listed in another thread please direct me to it. I've seen threads similar, but none of them list Missile Box and 3lb_f22. If anyone needs more information and detail that would help with solving this problem, please let me know. Thanks to everyone who is helping! -Zombie
