Henning,
Thanks for your help. I think Oliver has spotted the problem - inadequate permissions on
the firmware file. But I still can't understand why, after refusing to work initially
everything then came right for a day or so, only to then go back to failing to work!
Cheers, and thanks again for your efforts.
Regards, Alisdair
