Result !!
I downloaded the newer software for my camera from Ron's site, as per the link Smojo gave, and also outeredge's free winzippy software. Successfully unzipped the software, and while talking to Ron on Skype and following his expert instructions, it took all of 2 minutes to get the camera software updated & fully fixed and working. He certainly knows his stuff. Despite saying he didnt need anything for his trouble, I insisted on giving him a donation via Paypal on his website, as he's saved me from buying another camera. What a thoroughly decent bloke.
He highly rates Pakatak as sellers of little Acorn, they're cheap, the main importers, and carry all the different genuine models with a full warranty and repairs if needed by Ron.
