Does anyone else have problems downloading wirelessly with Zing?

I can’t seem to get zing to add any songs to my download manager.  I have Yahoo Music To Go, but when I select a song, album, mix, or playlist, it tells me that it has been added to the download manager, but if I look at the download manager under music library, nothing is ever in there.  I just recovered the device, so it is a totally clean install.  This is very frustrating, as I’ve always had problems running YMJ on this vista box here.  I would really like some tips on what I’m doing wrong so I can get this to work.

 I have the same problem except it only happens with some songs.
