Another possibility is that if you haven't already, you need
to adjust your Flash security settings on your computer (but I
think there's usually some kind of warning that tells you that your
computer is blocking the Flash content). Go to the
Flash
Security Manager and add the drive (such as C:) where you are
generating your output to as a trusted location. I had to do this
myself once upon a time.
A question: Are you seeing empty spaces where the navigation
should be, or do you see just the help topic taking up the entire
browser?
If you are seeing blank areas, try the Security Manager. If
you're seeing just the help topic with no blank areas, then it
sounds like you're opening some .htm file other than your start
page.
