Sorry, didn't spot these errors at the first glance.

This one is only a problem for the MIDI output; you have to specify a 
volume (like \f, \mf, \p ...) before _and_ after a crescendo; otherwise, 
the MIDI engraver has no clue how far to raise the volume.

Yet, I've no idea for the last errors; but I suggest that you always fix 
the easy problems first. :-)
Then, feel free to cut the input down to the minimal code producing the 
error, and ask again.
