Can't return Ebooks!

[chefwes]

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 4.5.6.177148 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!
