Unsolved getting flexbody mesh in game

i'm getting the mesh of my body in game but I can't get it to work and show up. any ideas?
file for examination if needed:

 

I'm going to start working on mine next week. If I can figure it out I'll give you a hand

 

Are you trying to put a different mesh on an existing car?
If so, it might not be showing up because it cant 'connect' to a jbeam node, or, you made a small mistake with names and reference points in the jbeam.

 

I’m making a vehicle from scratch and want to put the mesh the body mesh from the dae file on it. What mistake didd I make with the reference points?
Thanks,
