I downloaded an acsm from Overdrive and tried to open it in ADE. ADE gave me the generic error # 2038 with a URL, so I clicked the URL and manually downloaded the epub file. It opens fine in ADE. It does not open in Calibre with DeDRM installed and can't be converted. Debug log attached. Calibre 3.38 on Mac, DeDRM 6.6.3.
Also, I tried dropping the epub directly onto the DeDRM Mac app and got an error saying it's not protected and can't be unprotected.
