If I remember correctly, when you're installing the Copia reader it does ask something about your ADE authorization and you're supposed to say no if you don't want to deauthorize it.
I find the Copia site and reader very troublesome, and the layout is not intuitive IMO. I was having problems opening up Little Caesar when I got last week; I sent CS an email and they replied, asking a number of questions. I haven't responded yet - couldn't be bothered right now
