3 days ago I installed your latest Flash upgrade on my Mac, OS-X 10.7. It caused all of the video content in my Facebook Game apps and on other websites to stop working. I got the error message: "Plug-in Failure" This even happened on the Adobe installation confirmation page that tried to show video of other interesting products. I was forced to uninstall the upgrade and re-install an older version of Flash. How can you fix this?
