I'm stunned. As I was finishing a course everything went hay wire. First all of my scenes renumbered to zero, then slides went away, and finally the Unhandled Textbox opens. It was a pure horrific eLearning domino effect. I don't know what happened. I can't of anything I was doing that was out of the normal course of building and animating a slide.
Can anyone give me answers; what happened? how can I prevent this from happening in future? what can I do to fix and retrieve my course?
