Can't view Adobe TV Video Tutorial (videos) in Win7 - IE11?

Hi Folks,

Strangest thing!   I can't view some of the Adobe TV Video Tutorials (Windows 7, Internet Explorer 11)?  Examples are as follows:

Photo Workspace

Preset Migration and Sharing

Checked settings in IE11 and they're fine.  All updates are in place for Adobe Flash and Shockwave Players.

Any suggestions.

With thanks, k
