The issues are Epub, I can import them into Calibre with no trouble. But, I had to change over to downloading the issues with the Nook Study app (I have vers. 2.1.2) for Mac. I previously used the Nook for Mac app to download them, but you can no longer download directly to your computer from that app.
I don't know if the newer version of Nook Study would have the same problems as Nook for Mac, but I'm keeping the current version of Nook Study I've had for a while now just in case (it keeps asking if I want to upgrade to the new version every time I open it).
