I've tried it already, didn't worked
Finally i've tried this link below : Adobe Flash Player - Downloads
and i manually downloaded the right link content in the page called " Download the Macintosh Flash Player 15 Plugin content debugger " directly on my desktop, then i opened up it and ran it. Perfect ! everything work now, thank to me
Unfortunately, I really don't know what "didn't work" means. Details helps troubleshooting.
While installing the content debugger worked, this is meant for Flash developers and you may experience unwanted behaviour, such scripting errors and others which will degrade the Flash experience for every day users. We advise every day users against installing the content debuggers, unless of course you're a developer and need the content debugging capabilities.
