Erreur E-ADEPT-USER-UNKNOWN sur le serveur d'activation

Hello,

A few months ago,I have bought a Kobo Aura One for my wife. To allow me the possibility of buying E-Books on multipled E-books shops, I have installed ADE. Everything worked fine.

Yesterday, I bought a second Kobo Aura One for myself. There were no problems to load the E-Books that I already had in my Kobo Account, as this doen't involve ADE.

But when I asked ADE to autorise this second Kobo Aura one, I got the error message E-ADEPT-USER-UNKNOWN.

Thank you to everybody who could help.
