this is the answer I found on Mac support forums that worked right away. The old flash player plug in was not removed by the new installer. copied to give post person credit.

I have a new MacBook Pro and I followed these instructions, downlonading and installing the new Flash plugin. But when I looked in "/Library/Internet Plugins" there was no folder called "Disabled Plugins".
However, I did see two versions of Flash:
_Flash Player.plugin with old date
Flash Player.plugin with todays date
I deleted _Flash Player.plugin and this fixed the problem.
