Beginner problem with PianoStaff

[Don Ravey]

 I've just begun to learn LilyPond and already have this problem:  when 
I try to use PianoStaff, LilyPond crashes without even writing a log 
entry.  I uninstalled and reinstalled LP with no effect.  If I remove 
the PianoStaff reference, it behaves as expected (although I can't get 
the results I want, due to my inexperience).  I am running LP 2.10.13 
under Windows XP.  Thanks for any help you can provide me.
