Close Adobe Digital Editions.
Click the Start button, and then click on the 'Documents' link on the right-hand side of the Start menu. Then, open the 'My Digital Editions' folder. Inside, find the 'restore' folder and rename it to something else (like 'restore.bad').
At this point, start Adobe Digital Editions and try to use an .acsm file to fulfill an eBook request.
thanks for the reply, Nanaky!
no 'restore' folder anywhere on my machine, but extrapolating from your idea, i deleted EVERYTHING, in all folders inside Digital Editions.
I started Digital Editions 4.5 and my library books then were listed, but each had to be Re-downloaded from the library, and i lost all my categories and all the categorization, as well as all the OTHER (non-loaned) books i had in Digital Editions.
i wish ADOBE would just tell us what does or doesn't work
Should work...i has not this problem after the update.
