I've been down that road to.

"Go to Start > click on My Computer > double click on Documents and Settings > double click on the folder with your username > double click on Application Data. Now look for a folder named LimeWire. This folder named LimeWire is your preferences folder. You need to open the LimeWire folder by double clicking on it."

I get to the point of opening the Application Data and it isn't there. I don't have that.

So I'm stuck again.
