If ADE used to download the book (and preferably authorized with your Adobe ID) is on the same machine and user as calibre/DeDRM, it should work.

If not you could try deauthorizing and reauthorizing ADE by deleting the registry key. Scroll down to "Troubleshooting reauthorization and deauthorization issues on Windows" on this page: https://helpx.adobe.com/digital-editions/kb/activation-errors-adobe-digital-editions.html

Or some have had luck using the DeACSM calibre plugin instead of ADE to download their books. (I have no experience with this myself.)
