Duplicate entries of all songs

When I play songs on my clip zip, I noticed recently that every song is listed twice and plays twice every time! THis is a new development. I have all my music on a small card not on the device itself. Except for the few music selections that came with the device, I have not put anything on it. When I plug my clip zip into Windows Media, the duplicate entires do not appear.

Has anybody experienced this?

There is a tutorial regading this. Check below.
