Hello Manutoo,
Since newest update has been released we (some players and me) are experiencing problems when "playing" online.
The problem is that we can't host or either join. When we want to join we come to screen where ping is showed and then screen goes blue (probably when hoster hits play). Here is link http://img68.imageshack.us/img68/8302/te2006000et3.jpg
When we try to host everything seems alright until we enter the game and then connection is immediately lost or we are waiting for player for ages and then lastly connection is lost.
I tried to do fresh install, but nothing has improved. I want to emphasize that problem came with latest update. Could you please help us? Thank you and hopefuly this problem will be solved so we can again enjoy playing this great game.
