I got an E-book from Saraiva(its like amazon). But I want to read it on Adobe digital edition, so i added the file to my library and suddenly a message came up, saying that The ebook i just added belongs to another account. When I double click to open the book another message comes up saying Computer authorization is necessary. And asks for the Adobe log in and password. But when i type my login and my password it says incorrect. What must I do?
