After downloading Shareaza to obtain movies from a 'magnet' site, Limewire started up and stated it was no longer the default, and then when I went back into Limewire it asked again if it should be the default and I lost all of the downloads that were in progress. Is there a workaround to change this?

Addendum: I found the files in an 'incomplete folder' but they were at '0%' instead of the download percentage already attained. What the heck is with that?
