Look in the options in iTunes and make sure that your iTunes library is set up to be shared with other applications.
The iTunes Library.xml file contains some, but not all, of the same information that's stored in the iTunes Library.itl file. The purpose of the iTunes Library.xml file is to make your music and playlists available to other applications on your computer, such as iPhoto, Garageband, iMovie, and third-party software, in OS X Mountain Lion and earlier. These applications use this file to make it easier for you to add music from your iTunes library to your projects.
By default, iTunes 12.2 and later doesn't create an iTunes Library.xml. If you're using OS X Mountain Lion or earlier or a third-party app that uses the XML file (like Cross), you need to enable Legacy library XML support:
2.From the menu bar at the top of your computer screen, choose iTunes > Preferences.
3.Click the Advanced tab.
4.Select "Share iTunes Library XML with other applications."
let me know if that solved the problem.
