When I originally saw this post I thought that it did not work as I did't read far enough. I tried it and I am connected.

For those who are having trouble connection to the Gnutella network using LimeWire, we have a potential fix. You need to delete your WHOLE LimeWire preferences directory. The directory can be found in the following locations:

OS X:
/Users/your_username/Library/Preferences/LimeWire

Windows:
C:/Documents And Settings/your_username/.limewire

Linux:
~/.limewire

Please shutdown any instance of LimeWire you may have running, delete the whole directory, and then restart LimeWire. You should be able to connect.

Thanks!
