Hmm, yes, according to the programmers guide, you should have
"numParts" and an array of "parts". I have no experience with packages
that are installed, but I wrote code that reads and writes packages on
PC and Mac. Maybe your package is incomplete or somhow non-conforming.
Have you tried to read other packages and their parts?

You could dump the contents of your package through the Inspector and
get a better idea of what is going on.

I rarely see any messages there, maybe once a month a three-message-
thread... .
