can't open .ly file

[Themis Matsoukas]

I  downloaded a file from mutopia but when I try t open in lilypond I  
get:

An unexpected error has occurred: (UnicodeDecodeError: 'utf8' codec  
can't decode bytes in position 204-206: invalid data)

The file in question is  
http://www.mutopiaproject.org/ftp/ChopinFF/O69/w10-h-moll-cfi/w10-h- 
moll-cfi-lys.zip. This contains two .ly files both of which produce the  
same error.

I am running lilypond 2.10.23-1 (vBuild from Tue May  1 11:50:24 2007  
on a G4 iMac (10.3.9)

TIA
