I have been having problems with adobe digital editions. When I download a library book using overdrive to laptop I get prompt to open or save. When select save digital editions does not open, instead a blank internet page opens. I have been having difficulty with my nook color giving error message that book had been returned and was not on file when I just downloaded the book . I have tried deleting and reinstalling ADE and removing and replacing authorization. If all fails I will replace with a kindle if they do not use ADE.
Has you try to open digital editon > Go to file > add to library and choose the download file?
