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).

In the meantime, we are working on transferring our ebooks into HTML format, and will keep you informed.
