Ether2dmx8 missing license key


I have an Ether2dmx8. I I’m planning on using it with may pc for a show. However only 4 universes are unlocked via the software. I figured I would update the firmware. In this process the Ether2dmx8 reported it is missing the license key. I opened it up and receded the sd card. It did not solve the issue. Somebody suggested on the Facebook page that I reinstall the firmware. Does anybody have a suggestion on how to solve this issue? Thanks!
