yes i tried reinstalling... this problem has been going on ever since i first installed this game now after a long period of time.
apparently, back when i was able to play the game they had GameGuard as their anti-hack client and only recently they have switched to X-TRAP... however these errors seem to also tie in with the HGW game watcher. im not sure if X-TRAP is having compatibility issues with certain OS or if HGW game watcher is having a compatibility issue with X-TRAP or if its something else.
^--- this is the link to the Crossfire Tech Support forum section if interested...
some people are having results by simply End Processing the HGWC.exe (HGW game watcher) and starting the game again and keep doing that until it works... they say it could be the server being too busy or something, but i have tried that at 4am (which is when most people should be sleeping) and im still not getting results. i think a more direct approach is needed to resolve this issue rather then a generic approach like reinstall, restart, reboot and the like.
