Dont have an xml I am afraid.
No the licence is good for Mach3
Does it have an E-Stop button? If yes then make sure it is out, some you twist to release others you just pull out. If it still doesnt help (or doesnt have an E-Stop) then you need to change the active state of the E-Stop. You do that from Config menu, Ports and Pins, Inputs then scroll down to E-Stop. Once changed press the reset and it should be fine, next push your E-Stop button to confirm it resets Mach, if it doesnt then looks like you have a fault on the E-Stop wiring so check that out.
