I cant receive map files in a multiplayer game

Hi guys,

Spirit of the bugs here. I usually play in gameranger, and i havent had before any firewall-ports-related issues until now.

Since some days ago, every time i play in a multiplayer game with new map, game gives me this message "you havent received files so you cant start game etc..".

The thing is if i place that map manually i can green up and start the game, otherwise i cant. My firewall is disabled.

what can i do guys?
