Error getting license. License server communication problem: E_ADEPT_DOCUMENT_TOO_SHORT

[hanušw53524314]

I can't load my bought ebook (EPUB/PDF) from Google Play on my PocketBook 614 Basic 2 using ADE. I tried versions 1.7, 2.0 and 3.0 . When I try to open it in ADE, I get this error: "Error getting license. License server communication problém: E_ADEPT_DOCUMENT_TOO_SHORT". I searched Adobe and Google forums and tried Authorization and De-Authorization 1000 times, installation and reinstallation of ADE 100 times, switching off firewall and antivirus, but it still does't work... Please help me.
