Damaged licence key

Hi,

I changed AD domain in my company. Upon opening my ebooks, there is a message on damaged license key so I can't access the ebooks.

I have uninstalled and reinstalled ADE but the problem remains. I have tried to unauthorize the computer but message says it's impossible.

I have these ebooks on other devices and they work.

Any idea how to get this working back on PC?

Thx
