adobe digital editions 4.5 deauthorize deleted ID

Hello,

I have ADE 4.5 for Windows, had authorized the computer with an Adobe ID that I now have deleted. Now I cannot deauthorize it, because it requieres the password, but because the ID is already deleted, I cannot complete the deauthorization and I am stuck, cannot log in with my new ID. I have tried to uninstall and install again, but still the old ID appears automatically and keeps being authorized. Can someone help me please? Can the app be somehow reseted? BR, Hanna
