I have been using digital editions for over a year with no problems, however today when trying to download a book from my library to it (something i have done many times before), i had the above message pop up and it willn not work. this happened on both my home computer and on my net book. i tried uninstalling and reinstalling on both, but when the setup is complete that message pops back up again. i am fairly frustrated since i need ADE to get books onto my kobo. Any suggestions?
