Well, the answer I got from support is... to put it mildly, unacceptable.

Dear [name]

I apologize for the inconvenience all versions of Blacksmith 3d Jan 3, 2023, are no longer available as well as the original developer. I wish we could do more to help. If you have any other issues, please don't hesitate to contact support.

So basically they are telling us that the software we legally bought from this site is... dead. Don't expect it to work,  like, ever again.

To say I am dismayed and angry is an understatement. I wonder if this will happen to Poser.  I wonder if I ever want to buy stuff frim here again.
