    Hi all, i have been having the same problem for months now, and recently had to reformat my pc in an attempt to fix it. it did for one night and now it is back to the same problem. i keep getting disconnected from a match lobby or getting a message of the match no longer existing though it has just been made. upon returning to the main menu i get unable to connect to relic server, error code 9. i then reconnect and try to rejoin a lobby and get the same or it gets half way into the lobby and i get kicked out. I have gone the route with support, opened all the ports, checking and adjusting any antivirus issues, deleted the entire game and redownloaded, verifed game caches. reset the moderm etc etc etc…… my friend really enjoy the coh series and are really bleak about this whole thing. if you could help in anyway, please do it would be greatly apprecitated.
