I downloaded a movie and it does not save it, I get "100% - waiting" how do I solve this and save the movie?

100% completed? If it's completed, usually restarting LW will fix it. If not, check through the video make sure it plays all way through & if it does, then move the file from the incomplete folder to a safe area. THen cancel the download.

If the file did not begin downloading at all, then .. is it a gnutella network file or a torrent file?
