Hi,
I did the tutorial of the pdf last week (newest pdf of december) and
there is a missing step exactly at this spot of the PDF. (or actually
a "not so clear change which needs to be made to run the tutorial
without any issue"). I didn't know of the google groups at that time
so I didn't post the issue here...
I can't remember exactly how I solved it but if you look at the steps
very precisely you'll find the issue.
Cheers,
