I'll go with the 'beyond mere mortals' idea.
If I were in your spot I'd completely wipe/reset the controller, start completely from scratch.
Allow plenty of time.
I see two ways to "reset" the controller. There's "restore to factory settings" via the front panel, and there is a (magic?) "reset" button on the rear of the front panel (see diagram on p. 57 of the manual).
Any idea which option to choose? (I suppose I can always try and see what it does!)
