Hello, I have this problem, I bought a book and got the link. Unfortunately, I authorized my access using my computer, later I deauthorized the computer thinking that I will be able to authorize using an ID. Since it failed, I tried my way back. My problem now is that, I cant even access the book I bought using the same computer that I authorized. I am getting the error " E_LIC_aLREADY _FULFILLED_BY_ANOTHER_USER." I was advised to uninstall ADE and install another one. This made my problem worse. My error now is "E_AUTH_BAD_Device_Key". Im so frustrated and need the book ASAP somebody help me.
