I´m puzzled you´re still using FlashPlayer. Is there any need for this erroneous piece of ? I banned it from my Mac many years ago.
Maybe disable it for the time being to load the Screencast.com player:
Wow! Ha ha, I thought almost all software had dropped needing Flash by now. Not laughing at you Uncle of course. Flash use to freeze my computer all the time and was constantly needing updating because of how much of a security hole it was. That's why Apple decided to drop support for it in favor of HTML5.
I really did laugh out loud just now though with Frank's statement.
