Hi, I created the AdobeID, installed and configured the DeACSM Calibre plugin according to the github page and used it on an .acsm file I bought from Thalia.
Calibre told me that it could not use the file. However there were no error messages when I used it on two .acsm files from the Adobe sample library.
Begrudingly I installed and used ADE. After I imported the book through ADE and into Calibre there was no error message when I opened the bought file again.
The file is slightly different:

instead of

If necessary I will install Calibre plus plugins on another computer should you need more information, but maybe I simply used the plugin for a use caseI was not designed to do.
I could not find any more information and did not want to open a possibly entirely unnecessary ticket on github. The probably unique and/or identifying parts were replaced with XXX.
