Right - so instead of just replacing the database. Maybe I should also be doing a full factory reset instead?
Whats strange is that the books DO show up - what would be nice if instead of just saying "these files are locked" the Kobo said something like "these files are locked - to user
xxx@xxxx.com - this unit is registered to
yyy@yyy.com". Would be helpful (ish, as both the unit and my books are registered to the same email address ).
