Hello JSWolf !
Thank you for taking the time to read me and for offering me your solution. I did what you advised me: I have :
- followed the procedure to restart the e-reader before connecting,
- installed the Kobo utilities (database check returns: OK
- set up a backup of the database as soon as the e-reader is connected.
For the moment, it's working well. I still wonder what the origin of this dysfunction was. A firmware update?
On the other hand, the ADE page numbers are no longer displayed in the margin, whereas when I used ADE to copy the books on the e-reader, they were present. But this is a detail of no great importance, and I thank you again for providing me with this solution.
Sincerely,
R.G.
