Problem with AdobeID in Adobe Digital Editions

[Pia257506130f2d]

My adobe digital editions is authorized with an adobe id that no longer exists (its my email spelled incorrectly, perhaps I noticed when I created the account and changed it but it didn't update on my computer). When I try to erase the authorization, it says the password is incorrect (although it works for my real email online). When I try to loggin to Adobe using the incorrect email, it says there is no account with that email. I also tried to deinstall and reinstall adobe digitatl editions. Unfortunately, it automatically had the authorization. 

All this is preventing me from accessing books that I bought. How can I udpate the authorization? Or how can I contact someone in Adobe to deal with this problem?

I had the same problem and followed a suggestion to make changes to my registry which fixed the problem and allowed me to authorize under a new adobe id.  Don't recall the link I used tho.
