Trying to get ready for the season and several songs that were used last year are coming up with an error message that reads "No decodable audio tracks" it says that song has either been removed from the devise or is in a format that cannot be decoded. Songs are in library and we're used last year. I tried deleting the player and starting over and now it will not let me access my iTunes library.  The screen simply swipes left to another blank screen.
