I keep getting the error: "error getting license. license server communication problem: e_adept_document_type_unknown" every time I try to open a book purchased in play store.
I'm using Adobe Digital Editions 3.0.86137.
I didn't have that problem with the last book from play store.
I've seen a few posts about that problem, but no solution. I'm a bit annoyed, as I don't know any other way to transfer that book to my nook.
Thank you in advance
