can't open any of my ebook in Adobe Digital Editions 4.5

[samt69733398]

I tried to click on the installed book but it say "unable to open the book. Errors were encountered in this item" in Adobe Digital Editions 4.5. I tried all the books in my library and it all having the same issue. I cannot open any of them in my iphone and ipad as well.

ADE SUCKS! This damn app crashes ALL THE TIME!  Literally was working one day and the next it goes belly up.  Will advise never to use.

Hi!

I work for a Health and Sciences Publisher selling eBooks and our customers experience the same issue.

Most of them have been able to download the book content, even navigate once or twice, but since a few days they have been unable to open the downloaded book on ADE 4.5.7. Some of them switched to ADE 3 in hope they'd be able to access the content once again but it does not work either,

They do receive messages telling them about downloading of the license, or about an unknown permission error (it's in french, I do not know the wording in english).

Would an Adobe Expert be able to look into this ? We have now several dozen clients affected by the issue.

Many thanks in advance,

Best Regards,

Pierre Durand
