You should understand there is no central server. The gnutella network is about individuals sharing. So perhaps a few individuals may have banned you from connecting to them but impossible for everybody to have. With millions of users ... I haven't banned you. I haven't banned anybody from connecting to me & not that many people do.

* Do this simple test for us. Using your browser go here: http://www3.limewire.com:6346/ The page should say ‘Your test worked!’. What happens when you go there?

If you can't get that page then either your isp provider has decided to block a range of ports to stop p2p use or its a setting issue or a hardware issue or a firewall issue.

If the test page worked then try deleting your LW Preferences folder whilst LW is closed; instructions here: Fixes for Limewire
