I recently went for Windows 7 to Windows 10, and reinstall all my software, including Adobe Digital Editions. Since that, I am unable to transfer epub from Adobe Digital Editions to my KOBO device and it seems to be because my PC has not been autorise. The problem is that when I try to autorise my PC, I receive the following message : "Vous pouvez accorder une autorisation à cet ordinateur à condition de ne pas utiliser un ID adobe déjà alloué à un autre ordinateur ou périphérique mobile". A translation of this message would be : "You can only get a permission for this PC if you use a ID Abobe that is not already used wiith another PC or mobile device". Can someone help me? Thank-you!
