Error E_ADEPT_DOCUMENT_TYPE_UNKNOWN: I can't download the ePub of a book that I bought on google play

I've bought an ebook with DRM protection on google play. I can read it online without problem. I can download the pdf version, I can open it with Adobe Digital Edition without problem.

I can download the .acsm file of the ePub version, but when I try to open it with ADE there is an error message: impossible to download, it says that is a communication problem with the license server, and the error code is E_ADEPT_DOCUMENT_TYPE_UNKNOWN:

I really want to read that book on my e-reader, what should I do?

Thanks

Hi,

Can you please confirm the ADE and OS version you are using?

Can you please try to re-authorize ADE and try again? If you still get the issue please try to download .acsm file again and check.

Regards,

Mayank

Windows 10, ADE 4.5.6
I've tried to re-authorize and re-download and nothing has changed.

Google book-support has aswered me that Adobe does not support the embedded font encryption format (in italian: formato di crittografia dei caratteri incorporati) used for that book.
There is any chance to finde a way to solve this incompatibility? The ISBN code is 9788830441019

Thanks
