    black screen when trying to play you tube videos


      When I try to play any youtube video all I see is a black screen.  I do not even see symbols for pop out screen, etc.  I have installed the latest flash player on my Mac OS X ver. 10.7.3 while on safari, firefox or explorer.  I have read elsewhere that many other people are having the same problem on their Macs & no one has found a solution that works.  Please help?
