How complicatd can it be to activate adobe id for adobe digital editions?

So that I can finally read the book on kobo aura that I bought this morning. Addid the way the guide told me. But not allowed to read it as reader says have no adobe id. Which i have. Since instaled adobe digital editions. Tried to activate authorization but does not work. And if not authorized then apparently cannot give my reader the authorization to read my books. Very weird.

Adobe customer help apparently cannot help. Their customer support sent me you this forum. Anyone tgat knonws
