Erase Authorization and Add a new Authorized User in ADE

[hillarym72979832]

In ADE the authorized user on my pc and ereader is incorrect.  How do I erase an authorized user from ADE 4.5.2 when I do not have the password for that user.  I am not able to add the correct user as the option is greyed out in the menu.

I was able to delete the registration from the registry and re-register.  No longer need this question answered.  Thanks
