No, the demo is fully functional with only a few things disabled, the things are max 100 lines of code in Turn, 500 in Mill, Run From Here disabled, Threading in Turn disabled and a few others I cant remember at the moment.
It sounds like you have the Jog Control switched off, have a look and see if the LED round the button is off, if it is press the button and jogging should be back
