I've noticed that with a few stories at the A03 archive the download and convert to epub doesn't quite work. They appear to work in Calibre (I can view the stories on the Calibre Viewer) However when I transfer the stories to my Sony PRS-650 I get an error message that says, "Page Error."
These are two stories that had the problem.
My current solution has been to re-convert the files to epub. However, I'm not sure why this happens to some stories and not others?
I also noticed that I cannot add multiple story links to the fan fiction downloader box because then they all have the Page Error message and I wasn't sure if this was related?
I downloaded the above links individually.
