I had the same problem the last couple of days and fixed it by going into the limewire folder (in my computer its found here) C:\Documents and Settings\Username\limewire -- I deleted the gnutella.net file -- downloaded a new gnutella.net.net file (
here)which I pasted into the limewire folder. Restarted my limewire and once again it didn't connect so I renamed the gnutella.net.net file that I pasted into my limewire folder gnutella.net -- restarted my limewire and after 30 secs up she came with an excellent connection -- HOPE THIS HELPS -- please let us know
Thanx
