E_ADEPT_REQUEST_EXPIRED

Hi,

I have successfully downloaded Adobe Digital edition, but cannot download by ebook.

A message pops up: Téléchargement impossible

Erreur lors de l'obtention de la licence. Problème de communication avec le serveur de licences: E-ADEPT_REQUEST-EXPIRED.

I already read the help section in the website and do not recognize the triggers supposed to create this issue as mine.

So how can I get my ebook?

Thanks for your help!
