OK well here goes managed to crack this on my own ;-))) and I hope it helps others. Got rid of the Error 29 by re booting. The calibration was working ok but the prompt diagrams for turning it stopped at the third stage. SO I ignored the prompt diagrams and did stages 4-6 by watching the flashing green , when it flashed fast I turned it even though the diagram didn't alter and it worked the calibration was a success, yeah! Must be a fault in the software coding. we know about these things as my lad codes for a living. hope this is clear if not let me know and I will try to make it clearer.
