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.
I uninstalled ADE and reinstalled and that fixed it.
I had a similar problem. version 4.5.7 refused to open .epub files under Windows 10 although the same files opened on other devices. I deleted ADE 4.5.7 and replace it with version 4.5.2. Problem fixed!
It is time that ADOBE got their act together and looked at this problem.
How do I download that version on my iPad? Ive deleted and reinstalled but it keeps downloading 4.5.7 version. Thanks
