First, does the ARC expire? Or is it yours to keep?

[blank274]

Mine to keep, or at least they always have been before and I have not been made aware of any changes.

If ADE 2.0.1 is authorized with your Adobe ID, installed on the same machine and user as calibre, and DeDRM isn't working, then try uninstalling ADE and deleting this registry key:

HKEY_CURRENT_USER\Software\Adobe\Adept

Always be very careful when messing with the registry. Reinstall ADE 2.0.1, authorize it with your Adobe ID, and make sure your book opens (or redownload it). Then add it to calibre and the DRM should be removed.
