I'm new to PubIt, and I uploaded an ebook for sale without realizing there were problems with it. I subsequently discovered the errors and fixed them, and uploaded a new version -- but before I uploaded the new version, a customer purchased and downloaded the bad version. Deleting it from his Nook and downloading again didn't work. How can he get a clean version of the book without having to purchase it again?
Usually putting the book into "Archive" for an hour or so works for me. After this time, I re-download it and its usually the revised version. I have had to repeat this process at least twice on one book, before I was able to get the newer version.
It would be nice if it would automatically update the contents when you sync your nook with BN. (hint, hint)
