Where did you get a gnutella.exe??
None of the files that I uploaded are .exe files... they're just text files (you can open them with Notepad & read what's inside them)!!

Did you set up a static IP address before port forwarding?

Just backtracking a bit - after you originally deleted LW's preferences folder (you said "turned off" but I guess that you mean you deleted the folder), did you have to go through LW's setup wizard all over again?
