same as me... i also tried the limewireother.zip in case some missing files which didn't worked again. after some searching on the publishers site, i found out that there are some compability issues on win2000; what a shame!!!
i will go on to use my gnotella client again. i thought limewire had a good deal with development made, after browsinf trough their entire site, but it seems they have to go and learn some more to do a full compatible tool.
i hope to see their w2k-fix release very soon. more and more users use WinMe and Win2k lately, so they have no choice other than to fix it.
