I changed my Adobe ID but in DigitalEdition is still the old one and I can't change it

As I wrote in the subject, I changed my email in my adobe account deleting the old address and it is all ok but in Digital Edition there's still the old ID and I would change it so I can activate my kobo, etc, but seems it is impossible to log out from wrong ID and enter the new ID or, anyway, the ID in ADE is still the old one...

Please someone could help me?
