Following this thread and am very distressed. I found both apps yesterday and love the elegance of Calibre, but it absolutely chokes and dumps on the epub file I am trying to convert to PDF. For some reason the AniceSoft app manages to get past what are most likely illegal syntax. The file was generated from RoboHelp and is incredibly massive but even a file the 10th the size from the same project still causes Calibre to dump. I do not want to support an illegal app but am really wanting a simple solution to get from epub to PDF (pls do not ask why
). Recommendations?
