Sorry to hear you paid for basic to begin with. LimeWire Basic is free to use as long as you want. If it were me I wouldn't Goggle it the first choices that pop-up when you Goggle it are scam sites. And they will charge you for a free program. Why don't you right down the URL below then you can go to the official site when you rebuild and get it for free.
