I simply changed my mail and now I can't activate a book

Hi guys,

Recently I updated my email address for Adobe ID. So today I open DE for a book and re-authorize my mac with new e-mail but now it can't let me activate the book showing me this error:"

Errore di recupero licenza. Problema di comunicazione con il server delle licenza:

E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER".
How can fix it?
