try to rename downloaded gnutella.net.net to gnutella.net

and than copy it there!remember to delete original gnutella.net file!
the limewire must be off !
than start it and wait a sec or two so it can connect!

if that doesnot work try to delete gnutella.net and than start limewire!

make shore that your firewall allows limewire to connect!

maybe you have more than one firewall!
I dont know but it worked for me! and now I have turbo connection!

or you try to download different vesion!
