Has anyone encountered this problem?
I just update my Rhino 6 to Version 6 SR7 (6.7.18210.11281, 7/29/2018) Commercial and all a sudden I cannot open a file that I have created last week.
The original error message was saying that the file is not a rhino M_archive. I thought maybe I should restart the computer and I did. Now the error message becomes XXX is not a Rhino File. And there is no preview of the file either.
