    Unable to download. Error getting License. License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN




      I'm trying to download an ePub book (Margaret Atwood's "The Handmaid's Tale" , which I purchased on Google Play Books, in order to read on my Adobe Digital Editions application on my Windows 10 laptop computer and so that I would be able to side-load it and read it on my dedicated ereader device (Pocketbook). The book can be read online on the play-book store and on the google play-book app on my android phone. However, I have been unable to download it on my computer.


      When the download starts I get the message that the book cannot be downloaded and that the file type is unknown (Unable to download. Error getting License. License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN:). Please see screenshot below:



      And then the application closes down:

      I have also tried saving it in my Digital Editions folder and opening it from my library, without any better results.


      The application has had no trouble downloading and opening other ePub books from Google Play store. The issue appears only with this specific file, which has an .ascm extension.




      When I contacted googleplay support, they finally suggested that the problem has to do with the Adobe Digital Editions application and that I should try downloading the PlayBook app or contact Adobe support. As I want to be able to read the book on my e-ink eReader device (Pocketbook), the PlayBook app isn’t much help. I'm quite disappointed.


      Below I have copied my conversations with the google-support team.


      Do you have any suggestions?


      Thank you in advance for your assistance,

      Thanks for contacting Google Support.


      Hope you are doing great! My name is Kait, I'd be happy to assist you with your query. I understand that you're unable to open the book in your browser. I can imagine how frustrating this could be for you.


      I'd recommend the below:


      Clearing cache and cookies


          Open your Mozilla Firefox browser.

          From the Tools or History menu, select Clear Recent History.

          Note: If the menu bar is hidden, press Alt to make it visible.

          From the "Time range to clear:" drop-down menu, select how far back in time you want to clear browsing data. To clear your entire cache, select Everything.

          Click the Down arrow next to "Details" and choose what browsing data to clear.

          Click Clear Now.


      Disable extensions


          Open your Mozilla Firefox browser.

          Go to Tools > Add-ons.

          On the right, click Extensions.

          To the right of the extension you want to disable, click Disable.


      If there is an issue while watching on one browser, have the customer try a different one.

      Hello Kait,


      Thank you for your prompt answer.

      Unfortunately, the problem has not been resolved. While I can read the e-book "The Handmaid's Tale" online, in the browser and on the Google books app of the Android phone, I can't download and open the ePub file on my computer (Windows 10), in order to read it on the Adobe Digital Editions program and side-load it onto my e-ink ereader. The file appears to be downloaded with an epub.acsm extension, but when I try to open it with the Digital Editions application, this message appears: unable to download. Error getting license. Document_type_unknown. Then the app closes down. Please see attached screenshots.


      Thank you again for your help.
