I have just installed Adobe Digital Editions on my laptop and Android device. To start with there was an authorization issue as it did not detect my Adobe ID (though I'll never know how!). So I deauthorized and authorized several times till it got authorized. But then, when I try to open the downloaded Google books,the .acsm file does not open and this prompt shows up.
Unable to Download
Error getting License. License Server Communication Problem:
This happens both on my laptop and my android phone.
P.S. I have been trying this because I would be more comfortable reading the book in other ebook readers, it would be great if someone can guide me with that as well.
