Of course, you’ll be able to update since you are a Premium user.
I just released this version 1.1.1 and so I’ll take a little more time for the next one. Unfortunately I’m busy at the moment with another project but don’t worry, I’ll do my best for coming back to my plugin development asap.
Anyway, my suggestion is to publish playlists using xml for the moment; try copying the code from the link that I gave you (above), and change the contents according with your needs.
Thanks for being patient Ray 😉
