I've just restored my computer from a back up. Everything was working before my computer died. Now I can't open any books in the reader library nor download any new books to the library. It says the computer is not authorised to preview this page. But if I check the Adobe Digital Editions program, the computer IS authorised. Nothing has changed for my device.
I'm running MAC OS 10.6.8, trying to connect to a Sony PRS-650.
Any suggestions gratefully received.
