Having bought and coming to terms with Data Bridge, I find many of the Feature Tours on your site do not work. For example, Data Assist Feature Tour - it plays to the end of the first video where it starts to introduce Primary components - Data Assist Wizard, changes screen and remains blank. This happens with several other videos. I'm using a Mac, and have tried Safari, Chrome and Firefox - all with the same outcome.
How can I view the full videos?
