No playable file for playlists

I can't get playlists to work on Serviio.
So far, I've just tried audio playlists. I exported my playlist from iTunes to my shared audio playlists folder. When I click on that folder in Serviio, it says "There is no playable file"
I added a new playlist to see what the log says. Here is a copy:

Please help!
Thanks!
