Thankyou one and all. I will be deleting the Sony garbageware tonight and loading Calibre. I live in hope that everything works.
One last point regarding my didgital editions library and the existing ereader library (Which seem to have been corrupted) Do I delete both these, digital editions only, or leave them? Would I be deleting the books/files or are they stored elsewhere for Calibre to find.
Once again many thanks
