Question to Mackie - is the authorisation process now working?
Louis:
This forum was created by Peter Holmquist as an alternative to the unreliable job Mackie was doing with their "official" D8B forum site. Since then, Mackie has completely replaced their entire user forums, destroying the original D8B database....along with pretty much every other forum sub-category. It'll be "wait 'n see" to see if they restore anything. I wouldn't hold my breath on that.
So, it's extremely unlikely that anyone from Mackie will read this thread and respond.
You'll have to email or call Mackie directly to get that information. If their system has been restored, they should be able to provide you with the codes tied to your machine. You'll need your Electronic Serial Number (ESN), found at the bottom of the authorization window.
