You need to update your flash player, and You do not download the Flash player from any third party, just use the repository. You'd best go to www.adobe.com, and update the latest flash player, download it, install it and restart you PC, that's OK.
Another way, you also can download the YouTube video on your computer and watch it on your computer with Youtube download such as Aneesoft free Youtube downloader.
