I have no idea how to help you, however ive noticed on the FTB forum, quite a few people have had problems with BoP. If you havent checked the offical forums out yet, i suggest that you do.
Also, one thing i will recommend. Before you try anything that affects your world be sure to back up your save. --- id rather reign in hell, than serve in heaven. http://i833.photobucket.com/albums/zz258/dazbuzz2/sig/KSH04.png
