The Newer Versions of LW have been a Royal PITA for Most everyone. There are several different things you can try.
I for one have given up on LW and use several other different programs.
If you want to continue to use LW, then we can try to get you connected. If you want to try another program, I would suggest Phex. It is also a Gnutella client. See My Sig for Phex
You could also go back to an older version of LW. See this Link
--OldVersion - Newer isn't always better !
