Alright, so I have a lot of .epub format things that I get from a site I go to. Don't worry, nothing illegal. I can open them up in Freda, and it works alright. The performance is good, there are only a few errors with the actual formatting, and so forth. I was told, though, that Nook can open up .epub as well. It opens them, alright, but it is just plain white other than the page number and chapter title. In other words, no text. I don't think there's anything majorly wrong with the file, it opens up in Freda.
