Unable to download. Error getting licence. Licence Server communication problem: E_Act_Not_Ready.

I cannot get an ebook I bought from a publisher days ago to download the .ascm file to my 8 inch Samsung Android tablet. I can see from reviews at the Google Play Store this a chronic issue and the app's rating is low. I got the ebook to download to ADE on my little iPhone, but not my Android tablet. I keep getting the following error message: Unable to download. Error getting licence. Licence Server communication problem: E_Act_Not_Ready. What is the solution??? There seems to be solutions for other MS platforms and iOS, but not for Android. Fix this bug!
