i-tunes library
 

Can anyone help?
I'm a very new Limewire user..in fact pretty wet behind the ears in just about every techy aspect.
I've been downloading music and up until recently my 'tunes' were automatically added to my i-tunes library thus enabling transfer to my i-pod. The downloads no longer transfer to the i-library.This is a very recent development.Any ideas why and how I make this as it once was...or any other solution basically?
Thanks.
