Adobe Reader not opening PDF Portfolio - Flash player error

I have Acrobat 9 Standard installed on my PC and I created a PDF Portfolio. Acrobat Standard can open that Portfolio just fine.

I also have Acrobat Reader installed (11.0.2).and have Adobe Flash Player (11.7.700.169) installed. Both Reader and Flash Player work fine independently on PDF or Flash content.

However when I try to open the PDF portfolio with Reader, I get the following Error:

:"To view the Flash technology in this FDF file; please install this version of Flash player that supports Adobe reader and Acrobat".

The Dialog box with the message above has a [Proceed to download page] button (which does nothing but bring up Reader with a black page), a [Learn more] button (similar behavior), and a [Cancel] button.  Both Reader and Flash are the latest versions as of today (4/16/2013).

Any help or insight with this is appreciated.

Thanks !

Bruce Dana.
