Lilypond-book question

[Edson]

Hi!   Im a beginner in lilypond, and im using the windows version, but when i try run lilypond-book, appears the follow message: "AttributeError: LatexPaper instance has no attribute 'm_'  ". The same occours if i change the file extension by .tex or .mulatex. Bellow follow the body of the file that im using:   \documentclass{article} \begin{document}   test   \begin{lilypond} \notes{a b c} \end{lilypond}   end   What's trouble?   Thanks for attention.   Edson Jr \end{document}
