Recently, within the last 2 weeks, my Adobe digital editions won't return books after I am finished reading them. I get the message "Error returning item. License Server communication problem: E_Adept_Request_Expired. " This is from my Version 188.8.131.52148 on my Windows 10 Dell Laptop. Help!
I have even tried uninstalling it and then reinstalling it. I have tried to erase the authorization (to try a new one) but it won't even let me do that!
Check if anything with time, date and timezone change on your System. If not seems one of this not right set on the server.
