Books purchased from B&N cannot yet be viewed in Adobe Digital Editions (they use a slightly different DRM scheme that ADE hasn't been updated to handle yet). For viewing this content for now you will need to use the B&N desktop software.
Thank you very much for the fast reply. Now I understand. It's only the ebooks with DRM that I can not open. I can open free, non-DRM books. I should have noticed that myself.
I'm getting the same error message for one of the many books I bought. I actually read this book using previous version of ADE. I upgraded today and I now get this message. Last time I accessed that particular book was a while back (it states that it was last read on Jan 28, 2009 but I've accessed the book from another computer/ADE (home) without issues).
Any idea what is happening?
good to know, but is there an ETA for support of the B+N DRM format?
I understand your answer to this problem, but 2 of my 6 B&N books open properly in ADE; the other 4 get the "document is licensed for a different user account" message. All 6 books were published in 2010.
Thanks for your input!
