Xardas - do other games work ? It looks like it's unable to get reply from the server. Maybe use some good firewall (ZoneAlarm, or Comodo for slower computers) and enable everything on router.
Possible solution I found on some website (For Ringwall's problem)
if you have mcafee anti-virus , please uninstall and restart the computer,
and then install Toribash.
(You can use a different anti virus, e.g. avg)
select your internet connection from the network connections (e.g. LAN , Wireless, etc) , then again right click on the internet connection > select properties > Advanced > Settings > select Exceptions > select Add Program then browse for Toribash directory and select the TB.EXE file, select CHANGE SCOPE and make sure that the first option is selected ( By Default) and click ok, ok, ok, ok and then restart the computer.
