Hi Shambler, I seem to remember Marc saying that it only updates the OS after it's loaded it into memory and carried out lots of checks on it to see if it's legit, before flashing the ROM.
Best contact Access Support though:

Hope you get it sorted.

A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
