Imported model bones break after save

Hi guys!
I'm having an issue. I've imported an FBX model to Daz3D, but the bones are not child of the figures, as you can see in the image.

Everything works fine, when I rotate the bones, the meshes rotates as they should. 
But once I save the scene and load it again, the bones loose their relation to the meshes. I rotate them but nothing happens.
Any idea how to keep things working after saving?
Thanks in advance!

I'm more surpirsed that it works before saving than that it fails afterwards. I'm really not sure how you can salvage that.
