For some reason uzureus shut itself down and when i try to run it termination strikes as soon as all torrents appear on screen.

Internet usage seems unaffected by whatever the problem is. The only interesting thing I´ve seen is my wireless connection to router via eth1 is showing as No DHCPOFFERS received when I look at
sudo dhclient eth1


Any suggestions on how to rectify this? Assuming it needs fixing in the first place...
