Have you tried other browsers? What happens with IE, Opera, Safari?

  I have tried chrome and IE ,  all I get ..is a black box ...

If flash player is installed on all browsers, try clearing the cache (in each browser) and rebooting. That's the only thing I can think of.

Try Mozilla Firefox (Safe Mode), or any browser with no addons.

I think you can contact the Youtube support for this issue. I have a similar problem before and contact with the support, they solve the problem.
