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”

Hi Jpizzo64,

Sorry for the very very late response, this message must have slipped our attention.

There is a possibility that the licence PCB came loose. Can you open the M2GO and check on the front panel if the small licence PCB is connected correctly and not loose?

I’ll pop it open and take a look. thanks for the info
