new hdd in pc (mirrored)

i got a new hdd in my pc. it was mirrored from the old one.

now i can't open my e-books. i get following error:

"Dokument ist für ein anderes Benutzerkonto lizenziert" (document is licensed for an other user-account)

but it's the right user account. i only have one!!! i also can't delete the authorisation in "adobe digital editions".

how can i register the the new hdd in my pc???  https://www.dict.cc/englisch-deutsch/%5BBr.%5D.html
