Sorry, I forgot to tell you my OS. It is 10.2.8 I have searched the computer for

/Users/your_username/Library/Preferences/LimeWire

and I don't find it. Where is it located? The Finder cannot find it. Oh yes, I did put in my user name, and not "your_username".

Limewire was working fine one day, and the next day I could not connect.
