Carta Musica

Carta Musica does not print treble clef, tenor clef, and bass clef as the opening menu suggests. It prints A letter. There is "Carat Musica - Unregistered Copy" printed between all over the printe copy Perhaps I should have expected this, but I DO THINK IT REASONALBE TO BE TOLD in advance that this would happen and I EXPECTED TO SEE HOW TO REGISTER THE COPY. I am STILL looking for how to register the copy. Please advise.
