I also have shot myself in the NK-1 controller by upgrading the firmware. I have read the posts about creating an ovrc account and adding devices. I created an account, and tried to add the NK-1 device. This is where I am stuck. My NK-1 does not have a label that has a service tag. It has mac Ids which does allow the device to be found but then asks for service tag that a appears to be missing in action. Does anyone know a work around (I did try to use the serial number, but no go). I do not have a dealer to call because once upon a time we were a dealer, but no longer.
