I am very happy with the reading experience that fbreader gives and rather dislike Adobe Reader. Of course the DRM'd ePub files would not open in fbreader until the DRM had been removed. Thanks to help received I found out how to remove the protection and I know it succeeded because Calibre would convert the ePub files to Mobi.
On the PB360, fbreader would open the file, but although it appeared normal in Adobe Reader, it lost all formatting in fbreader. The epub file would appear normal when opened in Calibre, so it must be something that I have done with fbreader. Does anyone have any ideas?
