I was wondering when the Smashwords-bashing would begin.

My preference would be for Smashwords to accept HTML files, since that's what I start with (my DOC file is actually a conversion of an HTML file), but I have to work with the circumstances I'm given.
My previous files - including a file without any table of contents - have gone through Meatgrinder without any problems, which is why it's important to me to identify the exact nature of the problem here.
Let me try to be more specific in my questions:
What does "element 'navMap' incomplete; missing required element 'navPoint'" mean?
What does "assertion failed: first playOrder value is not 1" mean?
