Please don't think that A Tea Spoon is being flippant with you. It is actually excellent advice! The subject of Blender and making rigged models work with DBPro seems to be a complex subject with a fair number of things that have to be done in a precise manner.
We do have a few Blender experts posting on this forum, but until they show up to offer up a detailed reply it's probably best to follow A Tea Spoon's advice.
I, too use Blender, but I am a long ways from reaching the point that you have reached.
Eternal student in search of knowledge. But will settle for the occasional epiphany.
