I am posting this info in hopes to help others....it helped me!
http://www.gnutellaforums.com/connec...onnection.html Thanks, I got things working. I did not have to do anything with my router. I turned off my antivirus (Norton), uninstalled the current version of LW, restarted, I deleted the preferences file, then reinstalled the new version (4.12.11), restarted the computer. Things finally started working.
Thanks all for help!
The key was deleting the preference file before installing!
