i got this fixed , i managed to get on to the adobe flash settings by going on a site which had a youtube video imbedded ,right clicked when hovering over the video then turned of the acceleration then switched it back on and it worked

 

Glad it all worked out. Thanks for posting the solution for others to use.

 

I'm glad I read this topic. I had the same problem. But, I had to leave hardware acceleration off. Turning it back on caused the problem to reoccur.
