2 days ago installed Adobe Digital Editions on my home desktop PC (Windows 7) and created Adobe ID (my email address) and a password to authorise this desktop PC.
Yesterday downloaded and installed Adobe Digital Editions on my laptop (Windows Vista) but without authorising the laptop. It downloads books as expected. I would now like to authorise the laptop. I have clicked on Help/Authorize and continued to the authorisation page, entered the Adobe ID in the second space and the password in the lower space, and clicked on the “Authorize” button. I get the message “You can only authorize this computer with an Adobe ID that hasn’t been previously used…..” How do I authorise it? I want to be able to download the same book onto both PCs when the book supplier permits this.
