Problem opening some .AMF files into Rhino7

I’ve gotten a couple AMF files that will not open in Rhino 7. No messages, no results.

The files are pretty simple.
Anyone know what issues might be the problem?

Hi Pete, I see that. I do not know what is amiss. I’ll get the examples onto the pile for the developer, thanks for those.
