Are you using Adobe Digital Editions 2.0.1 authorized with your Adobe ID and on the same machine and user as calibre with DeDRM?

[sbabcock61]

Adobe Digital Editions 4.5.7
Yes - the computer is authorized

[ElleKayEm]

Can you open it in ADE 2.0.1 authorized with the same Adobe ID?

[sbabcock61]

I installed 2.01
Help / Authorization show computer is authorized
Am unable to open E-Doc - "Activation Server Error" code : E_ADEPT_INTERNAL

I am still able to open it in 4.5 on the same PC

should I uninstall 4.5 ?

[ElleKayEm]

First, try de-authorizing and re-authorizing ADE 2.0.1. Open it and press Ctrl+Shift+D. Then authorize with your Adobe ID. If you can open the book, then try adding it to calibre again.

Resolved

Uninstalled 4.5
Reauthorized the computer by removing the Adept Registry key (HKCU/Software/Adobe...)

Brought the file back in and converted it to PDF

Thanks for your help - going back to 2.01 was all that was required

Good. Thanks for reporting what worked. If you're all set, you can close the issue.
