That's "Nook," not nooky
I took kennyminot's and others' advice while I was away and got to know the PE. Unfortunately, the PE doesn't want to know me

I got Moonreader working just fine--apparently an update occurred while I was in parts unknown. I downloaded Nook. I then downloaded several Nook for Android files, only to have them disappear from the Nook Liberry. The first downloaded Sample remained until I left the site--but disappeared from the library, as did subsequent downloads. Rather than the "downloading" message I got when the first Sample successfully made it to me PE, I got an instantaneous "This book has been stored" message--but the library remained empty.
I be wondering:

here be monsters?

In other words, is it possible that security interfaces are such that the MAN recognizes that the PE isn't a Nexus, and then, No Nook for You? Or any other app except the MAN

?
