Just reading through the manual again: the /d command forces the software to run in demo mode, so you definitely don't want that.

You want either /p with a profile name or /s with a serial number specified.

Version 1.211 should be fine with the AXBB but there's no harm in an updated version I guess.

Can you post a screenshot of the device connection utility showing your AXBB connected, one of the list you get when you start up, and one of the UCCNC root directory in file explorer?

Have you checked the UCCNC folder permissions and the licence file permissions to ensure its accessable? The licence file should be in the same folder as the UCCNC executable.
