SUBSIM Radio Room Forums - Game luncher problem!

I'm having a problem with "Ubisoft game luncher".My connection is stable and I've tried uninstalling antivirus and disabling my firewall,but it still can't recognize that I have internet connection.I even couldn't download patches through game.I don't have proxy,but i do have router.It worked before but now it only says:"An internet connection is required to play this game.Failed to connect to the Ubisoft master servers.Please verify that your connection is functional and try again." :damn:All other games are working fine.Any help would be appreciated.
