How try to open it?
Do you used Windows or Macintosh?
Which Version of Digital Edition do you used?
Which error message you get?
I am using Windows 8.1. I just put the Adobe Digital Edition 2.0 in yesterday so I assume it must be the newest. I click on download at the library page and it says it is already downloaded and it tells me to click on redownload and I do. I have clicked save and I have clicked open, but nothing ever opens. Am I skipping over something obvious??
After Thanksgiving I will take my laptop to the library to see if they can make things work unless I find out sooner at Adobe Communities. Thanks.
