After reading your post more clearly this time, I realise the downld has come across a problem. It means that the file's hash information which was initially downlded doesn't match with the actual file that you've downlded. There may be a missing bit or byte of information, so LW attempts to redownld that missing part again. LW will attempt to do this up to 6 times before giving up. Here's an explanation by SBerlin, LW programmer:

Try the song out, if it won't play, then downld it again. If it happens again, try to find a different source or copy of the song.
Also keep in mind this:
