An epub book purchased from Google Play Books, "The world according to physics" acsm file fails. The book doesn't appear in the ADE "last read column" and doesn't automatically present in "read" mode at the end of the (failed) download. Any attempt to access it causes ADE to "hang" or simply close. Other acsm files from Play Books and other sources are OK (screenshot inserted).
The Google support team has advised "We have investigated and has shown error was already caused by the Adobe Digital Editions and would very much suggest to have them check on your setup to determine the best resolution for this case."
Who manages and generates the acsm file - the publisher, ADE or Play books?
