BBeBook error

[einKI]

Hi

I wanted to convert a pdf to lrf file to read it on the reader so I downloaded BBeBook including all the libraries, set the classpath and started the program.
I selected in Book Filename the file set the book title and set the document filename to the filename the book should have.

But I get the following error message (a java exception)
"Error loading LRF file: message: "

But why should the program load a LRF file the program should create one
so I'm somewhat confused now.

thx
