Does KBookReader actually work? Or am I demonstrating Yet Another PEBKAC issue?

The tool loads fine but when I open an epub all I get is gobbledygook.

There is no handbook.

Before any Horshacks respond, yes I tried TDE Ebook Reader ported from FBReader. Kind of user hostile with the non standard interface. The design seems to presume a user has create some kind of library. The formatting is less than pleasing.

Installing both packages creates no epub file associations. Odd.
