Excuse the obvious inexperience please....

I have checked as many forums as possible for some simple guidance to no avail... I have successfully been able to use LimeWire to download etc and am rather enjoying the experience, however the one thing I am having bother with is sharing the files with i-tunes.

Having found all of the other posts on this I have as far as I'm aware exhuasted all possibilities regards to what could be wrong, but if some kind soul would maybe like to help....
