ok, I can see that those files are definitely not plain text, so it'll be hard to edit them with a normal text editor, like I suggested.
Well, the next thing that I would try, would be to use an HexEditor (to tweak binary files like that one) and look for any MiniMg reference, but this is becoming a bit fiddly and complex solution.
Were those Automap presets done by Novation or yourself?
If done by Novation, maybe the best thing is to ask them how to convert or update them to deal with the new Mini V change.
Sorry for not being more helpful on this
