I don't know what you mean by limewire site. You don't downld from LW, you downld from people like yourself.
Choose a location to downld. Then ... what you need to do is put the incomplete files back into the incomplete folder & make sure the downloads.dat & .bak files are included. Without them, LW will NOT recognise your incomplete files. You'd need to resume them from the LW Library window.
