MP3s don’t play

All of a sudden, Kodi won’t play MP3 files from my music collection located on a network drive. When I click on a file, I get one of the 2 following error messages:

1. Playlist: Can’t find a next item to play.

2. Playback failed: One or more items failed to play. Check the log for more information about this message.

I have played the same MP3s through Kodi before. Also, I don’t have a problem playing them using Windows Media Player.

Here’s a link to my log file: http://pastebin.com/hH1qwLZm

Update: I tried playing MP3s on a local drive and get the same problem.
