I regret to tell you you have become another scammed Limewire basic purchaser.
see
http://www.gnutellaforums.com/showth...threadid=28751 or a bit of it to see you are not alone.
Limewire basic is free of charge and is obtainable only from
http://www.limewire.com/english/content/download.shtml
Limewire Pro can be purchased for a mere US$18,88 but only is you want to get it.
Sorry you have lost so much from your computer, but in future, I'm sure you will be making regular back ups
