I have two books that used to open fine now neither will. It says that the files are missing BUT -
The files are located in the proper location -- /my digital editions -- .
If I go into the folder and click on it directly Adobe acrobat pro opens up and tells me the document requires DRM features and asks if I want to open it in Digital Editions. When I say yes Another dialog box open and says unable to open - Errors were encountered in this item.
This program used to work fine but have not used it in a while. No changes to the OS or other issues.
