If your using a WTFast and trying to go server with it. Maybe the server in WTFast that your trying to connect is broken. Try to switch in other channel of your WTFast. Or if you don't use a WTFast be sure your connection is running smoothly. I once experience that one
I experienced that issue a few months ago, all I did to fix it was run auto-update then restarted my PC. After it booted again I was able to connect. But that was with my old XP , don't know if the same thing goes for W7. No harm in trying though
Maybe your internet is not connected propely, first try updating the client, if it doesn't work try restarting your PC.
If it still won't work, restart your router, I'm sure one of these steps will help you fix the problem. Cause majority of the reason this happens to players is due to internet connection problems. Hope you fix it soon, goodluck.
u Opened Port's?
If Yes, U Was Opened Them On The No Right Place.
That's Make Your Game Crashing Every Time.
Try Decolse The Port's And Back With Replay.
Good Night / Good Luck.
