All your licenses can be found on the Your songs page. Until you've activated your license, your license is only a preview that doesn't contain all the information you need for a complete license. You'll find your licenses by clicking the song title of your registered and licensed songs in the Your songs page. The section can be found in the top menu on the Tracklib site, but you can also reach it by going directly to https://www.tracklib.com/yoursongs.
