E_AUTH_BAD_DEVICE_KEY_OR_PKCS12

Question

Previous discussions were for older versions of ADE.

I am running ADE 4.5.1.139278 and Windows 10 (fully updated). I am on a relatively new computer and ADE worked the last time I used it on 22 July.

Today when I download a book with ACSM I get the above message. Previous advice suggested de-authorising and re-authorising the computer. When I try this I get a message that effectively says I cannot do this and please try later.

What can I do?

Select the Adept key.
