Sounds strange about the printer. Don't know why that should have any effect on Limewire, but you could always try and uninstall the printer and then try Limewire to see if that may be the culprit.

BitTorrent you should check google for. Try things like "What is BitTorrent" or "How do I use"+torrent .. things like that.

Just wanted to say thank you to all that helped. Apparently it did have something to do with the printer. Just thought I would post back saying thank you.
