Hello there,
I have put a ticket to line6 for the problem of the microSD and he has answered me to disconnect the card to start the Hx Edit or Hx Native and reconnect the card. I have been referred to the solution that our colleague Camelot_one has discovered.
I am ashamed of the answer they have given me. That card is dedicated and cannot be deactivated on a whim. I do not imagine that every time I have to restart the DAW I would have to stop the world for such a ridiculous failure to control only by a small and easy correction of the way to handle the authorization of the product or whatever.
Sorry for my bad English, but I had to use a web translator because it is not my language.
All the best.
