Got the Nook HD as a gift. Downloaded library books last week, EPUB files, saw it didn't work with ADE so I sideloaded. Worked fine.
Today I downloaded new library books and put them on the reader doing what I thought I did last time.
Every time I try to open them I get the "Book has been returned." error message.
Someone take pity on me and walk me through the process of sideloading again? It'd be much appreciated.
I really, really, really don't want to use the Overdrive app. Considering that library books worked last time, I don't see any reason for them not to work suddenly besides human error.
