Problem listening to a downloaded file
 

I have previously downloaded files with no problem. I just downloaded 2 files, but there is no content in them. The only change since I last downloaded is that the latest version of Itunes does not show Limewire in it and has placed all my limewire files in a Saved folder in "My Documents". I am not very technical, but that is the only difference since my last download. Is there some complication with Itunes 7.6 and Limewire?
