Eh????
Limewire has never had, sold or required a "lifetime licence"
Limewire does not charge for downloads
Limewire is a p2p file sharing application.
It is available from
www.limewire.com where the terms are clearly laid out.
If this does not clear things up for you the possibility that you may have bought an un authorized version of Limewire from a site other than the official one, does cross my mind.
