Thanks so much, Julian. Your firmware worked well.
I was able to find an old XP machine. I used it to take the camera back to 1.05 to start, then incrementally built it back up to 1.14. I couldn’t get the VersionUp Tool to work on the XP machine, so I jumped back on the Mac and went directly from 1.14 to 1.26 and then to 1.30.
The camera is now working absolutely fine.
I certainly owe you a drink or a donation to your favourite charity.
Many thanks,
Ben
