Well, if you did what the error message suggested and tried to restore the H9s system settings by turning the H9 off and then on again with the right footswitch and the HotKnob switch pressed (the switch in the upper left hand corner) and that didn't help, you may want to reinstall the H9 software over USB from a desktop using the Eventide Direct Updater app. That app can be downloaded here:
By the way when you turn your H9 on, does the display light up immediately, or is there a 10 second delay before the display lights up?
