Unable to Deauthorize

[Guest]

I have been trying to deauthorize my Adobe Digital Editions account for about 24 hours (I need to authorize a different username). Each time I make it through the dialogue, the error message "Unable to Erase Authorization. Please try again after some time" pops up. Why might this error be occurring? I have also tried uninstalling the program, but it keeps me authorized with the original username.

YES! after trying all the other things above, this fix was the one! Thank you!!!

BTW, I couldn't delete the registry key in my case, but the fix still worked.
