I found this fix from a Google Search. I have uninstalled and reinstalled Flash before on a computer to fix a similar problem. See Below.
had the same problem as well... And for the life of me could not figure it out. I uninstalled (or at least thought I did in "Uninstall Programs") Flash and reinstalled it to no avail. Then I stumbled upon another site that led me to a solution. Turned out that you need to reinstall Flash 10 or newer; but with a special uninstaller. 1.Download a Flash uninstalled from http://kb2.adobe.com/cps/141/tn_14157.html. 2.Close All IE windows 3.Run the uninstaller 4.Goto http://get.adobe.com/flashplayer/ and reinstall the Flash player again.
I went through those steps and it worked for me. Good luck!
