Maestro Invalid Serial Number

I have just spent a good chunk of Sunday trying to help my friend EA3AWY with his Maestro.

Jose Antonio bought a Flex 6300 a while back and a Maestro 4 months ago. Both worked great for him which led him to want to upgrade to a 6500.
The 6500 has been a bit of a nightmare. It was defective on delivery, no power output. It was sent to Germany and a month later he got it back. It works fine now.

However, it will not work with the Maestro.
He gets this error:

We tried downgrading to 1.7.32 and still same error.
It doesn't work with v. either.
We tried WiFi and Ethernet and direct ethernet to the Flex 6500.

He doesn't have the 6300 to test to connect to it as it was sold.

We can think of 2 possible causes for this.

1. The Maestro is somehow tied to the 6300 serial number and when trying to connect to a radio with a different serial number it won't allow it.

2. The fixes performed in the brand new 6500 when it had to go back to Germany involved changing the motherboard in the radio and there is an issue wit the internal serial number that throws the Maestro off into that error.

Jose Antonio has already opened a Help Desk Ticket, and I am sure Flex will respond, as they always do, and find a solution for him, but we are trying to figure out if someone can come up with a simple solution that he can perform to use the Maestro.

As far as I know, there is not a Factory Reset procedure for the Maestro.
Also, the Flex 6500 works great while accessed with SmartSDR for Windows in the latest available software version.

Any ideas??
