Sansa CLip Zip will not receive music. Please Help

Yes rhapsody uses protected files. I have tried the clip in msc and mtp mode and auto detect neither work. I’m thinking it’s an internal software issue with the clip itself. When I transfer the progress bar tha shows the clips storage space doesn’t move at all. It’s as if something inside the clip is blocking data from getting in. Then I’ll look inside the clip via my co.puter and I see the music files burl when I open them they are totally empty. This is so infuriating!
