Thanks, guys. I've sent a note off to nga.enquiries to see if they can shed any light on it, as up until recently, cab 80 was set to be enabled. It could be a delay, they may be doing the cabs in a phase (closest to a-roads first, working inwards), or (and hopefully not!) they may have decided not to enable my cab. Either way, I'll let you know when I know. Fingers crossed.
