I think the issue is there must be a space or nothing before before the book name.
Instead of 01Gen001.mp3 it needs to be this 01 Gen001.mp3 or this Gen001.mp3.
We will fix this issue for the next release of Bible Analyzer. Unfortunately, the file names must be changed to work with the current version. There are several bulk file name replacement tools available that will make changing the file names relatively quick.

But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. (Rom 4:5 AV)
