CONNECT - Example videos don't show

When trying the MetroStation examples, the video player opens, but there is no content. I see the video files in "C:\ProgramData\Bentley\CONNECT Edition\Configuration\WorkSpaces\Example\WorkSets\MetroStation\Standards\Videos\".

_MSTN_WORKSPACESROOT is defined to be "C:\ProgramData\Bentley\CONNECT Edition\Configuration\WorkSpaces\".

Could this be a security issue with Windows 7 ?
