I was a huge user of peanutpress, which became ereader.com when bought by Palm, which was then purchased by Fictionwise, which is now owned by B&N. Confused yet?
Anyway, I have hundreds of books in this format. I was amazed that even though this is the .pdb format that B&N uses for their online store, the books don't work correct on the nook! Some of them will open, but none of them display the meta data correctly, and of the 5 I tried, only 2 would open and authenticate properly. Yet they all open fine in the reader software on my Mac.
I haven't gotten any response from B&N's website so far, and haven't had time to call. Anyone else having these issues?
