Problem with CyberWar Games from Symantec

I have created a Blog post about the Symantec "Cyberwar Games" on YouTube, but there seems to be a problem. Other YouTubes work ok. Could it have been hacked?

The link is at http://www.northampton-marketing.uk/blog/ The start scene for me just shows code, with "Kali Linux"
