This may help:
This new "Gnutella.net" file, replaces your old gnutella.net file located which is usually located in "C:\Documents and Settings\Username\limewire"
Simply download the new file, rename the old file to "gnutella.old" and finally copy the new file over to your limewire folder. Don't forget to rename the "gnutella.net.net" (if it downloads with that name) file to simply "gnutella.net".
