Could you please try upgrading your flash player and check if it works. Here is the link - http://get.adobe.com/flashplayer/

And if it does not work, please update your JAVA Runtime Environment.

Also, please try to open the video from another laptop and see if it works. Thanks

The videos seem to work fine for me.
My laptop flash player version is 17.0.0.134, the Java runtime is version 7 Update 67.
I was able to use IE 11 64-bit or Chrome 41.0.2272.101 32-bit browsers.

Sounds like you just have to update to the latest version. Chrome 32 bit should be more compatible than its IE 64 bit (due to IE's dependency to run Shockwave Flash object 64 bit component).

Thank you Dezyre and Lin. I installed JRE and its working now.
