This tells you that you haven't lilypond-mode installed or your Emacs
can't find it.  Lilypond is not a standard mode that gets delivered with
Emacs, you have to install it seperately.  Since you said it worked
earlier for you, do

M-x locate-library lilypond-mode

in the _old_ Emacs installation to find out where it is installed, then
copy it over to where the new Emacs is looking for it.

This doesn't have anything to do with the issue you're having.

You don't need to look there, either.
