Animation file problem.

I'm not sure if the server will let my post through. I have a question about this little annoying problem I'm having. I got some animations from this site: http://www.studio1productions.com/Animations/space_1.htm

In which I'm hoping to use in Animation Shop 3, however it refuse to open it, stating that the file has no supporting or something.

I havent found anything that explain this problem, or I've overlooked it. X_x

So... Help?
