DMX disabled due to license error


I’m the Production Manager at the Fremont Street Experience in Las Vegas.
I run 3 outdoor stages here.
We use martin consoles, 3 M2go and 2 M1 usually with no issue.
On one of the M2GO’s started giving an error message once the show file is loaded saying License doesn’t match configuration - DMX output is disabled. I dont have it right in front of me but it is something to that effect.
I was running version 3.7.881 so I decided to change over to ONXY - I loaded the latest version and that went seamlessly but the same error comes up every time I load a show file.
I’m the original owner of this console and never have had a license error come up before nor on any other desk.
I have searched for an answer but it eludes me. Can anyone here enlighten me on what I need to do?
I’m a sound engineer by trade, lighting is not my forte so any help is appreciated.


The actual error message is
“DMX ERROR - this console has not detected the correct license key and DMX output is disabled”
