When I initially tried to update the firmware the version of the installed firmware, read 0.29. Then I got the error message shown above. I am using the Native Instrument USB-C cable that shipped with the keyboard for power supply from my computer and data transfer. When I started the process the screen on KS88 display a message indicating an update was in process. Then the above message on KSMK3 updater app popped up. Meanwhile the Keyboard screen still indicated the the update process was taking place. I thought I might have been frozen, however the lights on the keyboard were still changing as if a process was taking place. I decided to follow the direction in the popup window, by first powering off the KS88 keyboard then unplugging it, then plugged it back into my Macbook When I powering it back on, the keyboard displayed this error message. When i restarted the updater app, the installed firmware version display 0.1. I tried all the troubleshooting tips accept changing the cable. I even connected it to the dedicated power source on a power strip, so the NI USB-C cable can solely perform data transfer.
I was really looking forward to seeing what NI had to offer for making music and purchased 2 upgrades to get K15 Collectors Edition along with this keyboard. So I am truly trying to avoid sending this back. Can someone help me please?
