Don't use both Norton & Windows firewalls together - they'll conflict with each other. Turn off the Windows firewall & configure Norton to allow LW. Restart your computer.

If that doesn't help, find out the brand & model of your modem/router...they often have their own internal firewall & that might be why you can't connect. If you connect wirelessly, the router might be in another room. If nothing's showing on top of the device, tip it upside down & have a look underneath!

Also, go & find the gnutella.net file (as it says in the sticky)...what size is that file?

If you're still stuck - did you delete the prefs folder & try an earlier version of Java?
