automatic downloads from limewire to itunes

[magnum44]

On my macbook pro when I downloaded a song in limewire and clicked explore it used to automatically add it to my limewire playlist in itunes but last night it stopped doing that. I cant even drag a song into itunes now, what do I need to do to get limewire to automatically add my song to my itunes again when I click explore? I got a message saying I had to go into itunes and click something under files, if anyone could help me I would appreciate it, this is very frustrating
