Hi everyone. I recently purchased 5 digital books from Barnes & Noble and was able to successfully de-DRM all five of them. All 5 books were downloaded from B&N in ePub format.
I'm having a problem with one of them while running through calibre to add metadata & do some surface "touch ups" before I upload it to my iPad. I get the "Failed to convert" error code in calibre every time I try it. Here's the log of the specific errors. Any help deciphering this & a workaround is much appreciated!
