austinma62,

Double check that your Vista firewall's still allowing LW.

After you deleted the preferences folder & restarted LW, did you go through the setup wizard all over again?

Did you make sure that LW was properly closed before replacing the gnutella.net file?

Did you have any trouble with any of the fixes?

What is the model of your 2wire router? In LW go tools > options > advanced > firewall... do you have UPnP selected, or manual port forward, or is 'do nothing' ticked?

ladyshadowmoon,

Did you go through all the fixes in this thread: If LW Will Not Connect

Did you have trouble with any of them? After you deleted the preferences folder & restarted LW, did you go through the setup wizard all over again?

Did you make sure that LW was properly closed before replacing the gnutella.net file?

If you're sure that you've tried everything, please give us your system details, as per that thread.
