Can someone help me understand what does following error mean?

I get this error during Publishing my project.

I encountered the same problem and notice that it happens whenever I include a Smart Art diagram and tried to perform animation of these objects one level at a time.  When I remove the animation, I could publish successfully.  It seemed like Articulate is having problem processing these objects.
