How solve problem not being able to delete old autorisation Adobe Digital Editions at my laptop?

[Marleentjepeentje]

Hello, I have bought a digital book but cannot open it with Adobe Digital Editions at my laptop. I did change my emailadress at my Adobe account to the same email adress as bol.com, where I bought the book. Bol.com told me to do so to be able to read the book at Adobe. The problem is that I cannot delete my old autorisation with my old emailadress in the Adobe Digital Editions programm. And therefore, I still cannot read the digital book I bought. Please can you give my support.

What version of Digital Editions are you using?  When you say that you cannot delete your old authorization, what do you mean, exactly?  Are you getting an error?
