If you are unable to open the videos, please try the following:

1. Did you unzip the zip folder first? Instructions here: http://www.wikihow.com/Open-a-.Zip-File-Without-Winzip

2. Do you have a video player installed? We recommend Windows Media Player 12 or Quicktime Player.

3. Do you have your computer set to open videos with your video player? Instructions here: http://www.dummies.com/how-to/content/how-to-open-a-file-with-a-different-program.html

If none of these work, please open a support ticket and let us know if you are receiving any sort of error message, what that error message is, and send a screenshot, if possible.
