2Download the file called Material_Library.zip from the FTP site and extract it into your folder.  Then double-click on the HTML file to play the video back in your browser. 

I like to use project-specific material libraries and material libraries that store types of materials; such as bricks, concretes, or would materials, for example.  The material library files are small and the issue becomes more a management concern.

Good luck and have fun
