If you are unable to see the movie, then your Quicktime video player software is out of date. Go to Quicktime's site and download for free their newest software for Quicktime. It only takes a click and a moment. 7.0 is the newest version. One should do this occasionally anyway to keep up to date with technology.

Here is the site for PC:

and if you have a Mac like me:

You don't need to buy anything like the pro version, just free download.

Enjoy the preview!
