I downloaded a textbook for one of my college classes through Adobe Digital Editions. I have been able to read the textbook since the first day I bought it (January 15). However, I discovered today that I am no longer authorized to read it. Previously, I chose to authorize my computer without an Adobe ID. When I attempted to read the textbook, it said I needed to use the Adobe ID associated with the textbook. I have tried using my current Adobe ID as well as previous ones. I have not changed anything on my computer. I'm assuming because I did not previously use an Adobe ID to authorize my computer that that is why I cannot use it now to open the textbook.
Has anyone else had this issue after choosing to authorize without an Adobe ID?
