Cannot open DRM-book on Andriod device (Aldiko) and book no longer seen on My Adobe page

Hi!

I have a pdf e-book with Adobe DRM, that I used to be able to read on my Android device with Aldiko. Now I upgraded to Aldiko Premium, and I cannot log in to Adobe DRM there: I get the error E_AUTH_BAD_SERVER_RESPONSE. I have de-registered my previous version of Aldiko to avoid conflics.

Further. logging into My Adobe with a laptop, the book is not seen on the overview of my account.

What is wrong and how can I access this pdf-book again?
