Its not very often that someone posts a reply to their own message which offers a solution, but here goes...
I think I have a solution (if you live in the UK)
I have spoken to Datel and they told me that in some cases, the DVDR-X can corrupt memory cards.
They are offering a free service where you can send your memory card and DVDR-X to them and they will try to unlock your card and get your saved data back. They will also update the drivers.
Their phone number in the UK is:
(01785) 810 800
It should take approx. 1 week for the whole process. I'm going to try and send it recorded delivery just in case!
Hope this helps
