Could you please see the Flash Player installation status by accessing the following link: http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
Also, please let us know the Mac version and browser you use? From which website are you playing mp3 files?
I am sorry but the screen is gray and when I follow the directions to
install the Flash Player it says the installation is successful but it does
not show up anywhere on my computer. The Flash Player icon is on the
desktop but when I click on it there is just the installer. I have
installed 7 times all with the same results.
Thank you for you guidance.
