Is anyone using VCarve and exporting tool paths into Boxford software?

I'm using VCarve 9.5 and Boxford Vs10. When I output the tool paths in the dropdown .box post processor, I get a .fan file.

The Boxford software doesn't recognise the file, even when I change the name to .box.

Boxford sent me some lines of code to put into the program data folder in Windows 10, so I get a .box file, which they say will be OK.

I'm afraid I have no idea how to do this and they are not being too helpful.

Can anyone help?

Thanks for viewing.
