Thanks Sassanik, I had actually just worked that out before you so kindly replied.
I have upgraded the software to the 1st December version 18.104.22.168 rar as advised and it worked beautifully. It is certainly much better software and I am pleased to say that I have succeeded in copying my ADE books back directly off the SD card.
The menus are far superior to 1.12.6 and the operation is smoother. So off on holiday tomorrow with it working just in time.
Thanks also to Code Monkey for the help and advice; will keep an eye on the forum whilst away (because I'm a sad person!)
