RGC DISCONNECT ME

hello, i need help please
i have been playing on RGC long time ago and everything was good, but lately actually since yesterday and today it disconnects me from the chat server after about a minute of opening rgc so i cant join a game and it says something like you have lost your rgc connection and if you are not in game restart your rgc, but the thing is i m always connect to the internet.
So whats the prob ?
Thank you in advance. :-)

There could be a firewall issue between your RGC Client and the conflicting program, I Suggest allowing it in all firewalls/anti-virus programs you possess.
