I transferred a DRM protected PDF to my iPad and now I want to open it via Bluefire Reader on the iPad. When trying to open the PDF, I get a message: " Add Account: This application is authorised with the following user accounts: (here goes my user account xxx). This item (i.e. PDF) was originally downloaded with a different user account or Adobe ID. To continue, please add that account". I don't understand why. My Digital Editions has the same Adobe ID as the Bluefire reader.
When I installed Adobe Digital Editions for the first time I might have not authorised my PC straightaway but later I did that.
Please help, where is the problem?
I would very much appreciate your suggestions how to solve the problem I described.
