I've done everything you have suggested and still nothing has changed. Let me know "FRIENDS" if it helped your situation.

I have just reinstalled Limewire in the hope it might fix itself, and discovered an error message saying this,
"Limewire was unable to start the Digital Audio Access Protocol Service (for sharing files in iTunes). This feature will be turned off. You can turn it back on in options, under iTunes -> Sharing."
This error doesn't appear on my desktop. I'm wondering it it's part of the problem...but I don't know how to fix it if it is.
