Authorization Needed

Hello, I have a huge problem with Adobe Digital Editions. Adobe Digital Editions received error, "the vendor is not associated with the item you are trying to open"

This error happened after I installed the newest verion of Adobe Digital Editions.

I have not changed computers.. but I have done a clean install of the newest Adobe Digital Editions and authorized the computer using the same account on the same computer. Adobe had accepted the authorization. But now Adobe won't allow me to read any of my DRM ebooks, Why? What can be done to fix this?
