Someone has raised a query on the MAC. Looking at the notes I made at the time indicate that it should be that as corresponds to the info in the file called mac which I provided.

The information which I included in the README.txt is clearly wrong. Quite how it got that way escapes me.

Are you able to try this and let me know, please?

Post edited to remove displaying the actual MAC from view on a public forum.

Update, I have had confirmation that this now works.
