January 2021: Problems playing videos.
Since Adobe removed Flash player from Adobe Reader a few days ago, some people may have problems playing the embedded video in our ebooks. Our videos are not Flash content and Adobe had assured us they would be adding a new video player to Reader, but so far they have not done so.
If you are having problems, please contact us at [email protected]. We can send you the videos as separate files.
Dropbox on tablets and mobiles WILL still play the videos. So will Adobe Acrobat Pro (at time of writing).
