After I installed the last flash player version (30.0) i can't watch one site (WSL)

To provide assistance, please provide the following:

• Operating system version
• Web browser and version
• Flash Player version
• Explain your problem in step-by-step detail if possible
• A direct link to a web page that demonstrates the problem
  • a link to the exact content, not the top-level site URL
• If you get error messages, please provide a screenshot

A lot of the online video these day is HTML5 video, not Flash.  Please confirm if the video you are attempting to view is indeed Flash video and not HTML5 video by right-clicking on the video.  If the Flash context menu does not display, it's not Flash video.
