On Sept 13th 2016, Adobe released update 23 of the Flash Player. This update includes a change to the default security settings that may prevent successful playback from a local CD. If you see a long-term spinning circle ("Loading...") or a "Connection Error" when viewing any part of a video, please follow the Adobe Flash Configuration Instructions below to correct the error.

Apart from Adobe Flash itself, Microsoft, Google, Apple, or Mozilla may make changes to default browser settings as they release different versions of their web browsers. In some cases these changes may prevent Flash movies from easily playing from a local CD.
After completing the important Flash changes listed above, if you are still unable to play any video, or find a video that seems to hang or displays an error, please visit our Help with Videos page for additional corrective steps.
