Thanks jhowell. Sorry, I didn't think I was asking anything wrong as the book belongs to me under my Kindle Unlimited membership and I don't even know if it is a DRM problem as the other Kindle Unlimited books open normally.
UPDATE: I've solved the problem now anyway. As well as reinstalling my K4PC v1.17 ... I also uninstalled the update to Calibre (to 5.3) and reinstalled my previous version of 4.23 and the KU book which wouldn't open, does indeed now open. So, all sorted and hope it was ok to post this update here. Thanks.
