I'm going to grab me a copy of this also and store it for safekeeping.
A shame it was killed though: despite HTML5 being the new and preferred way to go, there are still many legacy sites out there using Flash, and lack of a plugin will make them all but unusable. Having been in web applications development in the past, I can easily say that many site owners had no idea what they were getting into, wanting a "flashy" (no pun intended) site that unknown to them, would leave them trapped. To edit a Flash site, you need to edit the original work files and republish the finished Flash file; it is not like editing a line of text in a standard HTML-based site. A lot of these owners are trapped, IOW, and changing over from Flash will take quite awhile and also be expensive for the site owner, as the ones built solely around Flash would need to be completely rebuilt from the ground up. (This is why I always discouraged clients from using Flash...)
