Hi there - can't find my particular problem when searching but if there's a fix just point me there.......

I've recently reflashed my n900 and re installed nqaap - in order to avoid all my audiobooks jamming up media player playlist I've placed them in a file I've called audiobooks and hidden it from the index system. I've pointed nqaap at this folder and it sees the audiobooks and apparantly loads them. However it doesn't play them. I've loaded panucci too and it doesn't either - am I missing anything obvious?
