AXBB-E - computer communication problem

[Evans]

I've made and wired up my electronics enclosure.
I need to activate my UNCNC license and get my computer to communicate with my AXBB-E unit.

I have a windows 10, 16 gig ram laptop that I will use to control my 60 / 40 CNC
It has an ethernet port. I bought a new crossover cable and apparently the AXBB-E unit is powering up correctly.

The laptop will not allow me to change the IP to 10.10.10.10 sub 255.255.255.0 messaging that more information is required
It indicates that the AXBB-E unit has an incompatible IP address.

Connecting to my (windows 11) office computer allows the IP address to be set to 10.10.10.10 sub 255.255.255.0
However UCxxx cannot recognize the AXBB-E unit. When I try the blue link led blinks which I assume indicates that there is a connection. Both the green leds are lit so the unit seems to be powered up and working correctly (see photo)

The UNCNC software wlll only open in demo mode and there seems to be no way to activate the license key.

From google searches other have encountered the same problem.
I've spent about 12 hrs trying various ways to sort this.
I've written to the supplier and manufacturer for advice waiting on replies.
Any solutions would be greatly appreciated.
Thanks Evans
