Yes it was davidfor, and old Compaq (HP). The new machine is on Windows 7.
I've installed the Kobo utilities plugin and set up the new columns, but am not quite sure how to import the existing status of books on the Kobo into Calibre (eg whether read). I looked through the Help file, but it seem to refer to correction of problems, but not importing data from the Kobo?
Do I use Update metadata in device library?
EDIT: I think I found the answer
here. But I got :
ERROR: Unhandled exception: <b>OperationalError</b>:no such table: ratings
