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."

All other games are working fine.Any help would be appreciated.
