Invalid Serial number when registering Ur 22 MKII

I just bought a UR 22 MKII Audio Interface. When I attempt to register it on the Steinberg website I keep getting the message that my serial number is invalid. I’m reading it write off of the box and the unit so I’m confident I’m typing in the correct number. Has anyone else had this issue? What can I do to register my product? Am I missing out on something if I don’t register it?

Thanks for any guidance and help. :slight_smile:
