I am very sad that it isn't, and I really wish that I'd figured out how to get an archival copy back when it was still available.

All the SWFs are archived (which is often not the case on Wayback). Just when the program is requesting to load one, archive.org is returning an HTML-wrapped file instead which fails to load. It would be quite easy to add to Flashpoint.

Managed to find them at:

will have to look into how to get them to play again....
