Elbow not bending with skeleton made with smartbody

I am using smartbody to create a skeleton of a 3d mesh that I have a scan (a human). When I am loading a bvh into that model, the elbow doesn’t bend so my arms looks like robots… If somebody help me resolve this I will be very happy…

Here’s a video of the problem : https://drive.google.com/file/d/0B_ZBy6q5jS8xR01YX2ZPNXA1Zk0/view?usp=sharing

Thanx in advance, merci beaucoup…


So nobody have an answer to that ? Do you think that upgrading to the newest blender version will solve the problem ?

I have try changing version with no success, do you think that’s because my skeleton is wrong or it’s because I am using Makewalk…
