I've already forwarded two different ports for Limewire, and tried both of them (6346 and 47000) at different times. Still, no result. Also, I've been running utorrent without problems for the last few days... I have to restart it every so often, but I can get speeds of up to 150 kBps.

I've installed 1.4.2 Java RE... don't know if that's gonna do any good. And I've erased my preferences once... and set it to run under Administrator... and tried setting it to run under Windows 2000. No success...
