Adobe Flash has reached it's "End of Life" and has been disabled on nearly all browsers and devices.

We are unable to support the older stories and games utilizing the Flash interface. We recommend getting the latest HTML5 versions from our website.

However, for those who are persistent. There are some alternative methods. These methods are "use at your own risk" and have not been tested or endorsed by the original authors or developers.
  1. Using the Flash Developer executable. This is available with older Adobe/Macromedia Creative Suites that contain the Flash developer application.
  2. Flashpoint.
