Hi, I can normally log into my Adobe ID from my browser, but when I try to authorize my computer in Adobe Digital Editions I get this error: "Incorrect login ID or password for the selected eBook vendor. Please try again". As eBook vendor I selected Adobe ID. The login ID and password I use are the same that work flawlessly while logging in from the browser.
If you used a special character or a umlaut should try to reset the password and used only numbers and laters (big and smale).
Ok thanks Nanaky that solved it.
You are welcome.
