Hello everyone
Yesterday I tried to join an internet game and it said I needed to download the latest version to play, so I downloaded that and the lasted patch just to be sure.
Since this it hasn't let me host matches anymore, the message says 'It seems your PC is not reachable, other players from the internet might not be able to join your game. Please check that UDP port 4321 is open in your firewall/router'.
I haven't had a problem hosting matches before this and my internet connection is fine.
If anyone could Help I'd really appretiate it!
