So yes, everything was fine last night. Log in today and BAM can't start a game up. Can't host, can't join.
Click to host, hit to begin, FA boots up, my mouse pointer is an hourglass over a black screen. Then the hourglass is replaced by FA's pointer, the screen goes a bit lighter as the backlights turn on full, and then... nothing. Nothing at all.
All firewalls are off, and got UDP error on login a while back. Turned on uPnP last week and have played plenty of games with that on. All fine until now. Logs attached.
