I bought an ebook from Google Play Books: I may browse it from within Google Play; I can download the .acsm file (either for epub or for pdf version); but when I try to open it in Adobe Digital Edition 4.5.5 for Windows I get the error
Error getting License. License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN:
Looking at the .acsm file I noticed the suspicious line
which is quite different from the one I got when loaning ebooks.
The only thing Google makes in such a case is to refund the book, which is not an actual answer; any idea of what's happening?
