[Peter Lavetti]

I can't even begin to use this application. I click on it; see the new file and 
save it; do Compile > Typeset file and then the 2nd window comes up with this:

Processing `/Users/peterlavetti/Desktop/Untitled.ly'
Parsing...
/Users/peterlavetti/Desktop/Untitled.ly:1: warning: no \version statement 
found, please add

\version "2.18.2"

for future compatibility
Success: compilation successfully completed

No PDF ever pops up. Nothing else happens. I have the manual, and I am trying 
to teach myself. I use Safari ver. 5.1.10 and Preview (that opens a PDF) ver. 
5.0.1 on a MAC OS 10.6.8
