Magic Music Visuals

Just bought the program...love it, but I'm running into a problem.
Ive tried to save work and gotten a pop-up saying that saving wasn't able to happen.
I think that some of the training examples have dropped off after attempting to save.
Ive created a new project, saved my progress, only to go back and find nothings been saved.
I'm fairly computer literate, but I'm feeling like such a noob right now!
Is there a specific way/method to saving that will work?
Sorry to bother y'all with such a basic question but believe me, Ive tried everything else and I keep losing work thats taken hours.

Thank you for your time!

Hmm, it sounds like you might still be running the Demo version? The Demo doesn't allow you to save. If you'd like, you can uninstall/delete it to avoid any confusion and make sure you are running the full version.

Thanks for the response!
I'll delete everything, empty the garbage, then re-dowmload and re-install the program.

Thank you!
