Several times I have installed and uninstalled Adobe Digital Editions. I get the screen, but when I try to use it I keep getting the message: “Error getting license. Server communication problem: E_ADEPT_REQUEST_EXPIRED”. The time/date on my computer shows current date and time. I have tried many times to install by using your site as well as my public library site and still get the same message. Please tell me what I need to do to get it installed.
