two days ago, I bought an ebook for the first time and so I downloaded Adobe Digital Edition (ADE). Unfortunately, when I try to open the .acsm-file in ADE I receive the following message: E_AUTH_BAD_DEVICE_KEY_OR_PKCS12
What I've already tried: I deleted KEY under HKEY_CURRENT_USER\Software\Adobe\Adept\Device. Afterwards, I tried to erase my authorization: ADE --> Help --> Erase Authorization --> password, confirm, confirm eingegeben I then get the following message: "Unable to Erase Authorization. Please try after some time."
I waited 24 h hours between two attempt of erasing my auorization and I still ge this message, so I don't thing time is an issue here.
I already downloaded the .acsm-file several times but no change.
Unfortunetaly, I don't have another ebook to test whether I have this problem with different .acms-files.
