I am trying to import books into Adobe Digital Editions. However, when I do this, I keep getting the message "Unable to download, Error getting license. License server communication problem: E_ACT_NOT_READY". So I followed directions and was told to erase the computer authorization. However, when I tried to do this, the email account that shows up I no longer have access to and I don't remember the password for that account. How do I erase the computer authorization in this case?
