Model rigging destroying model

[TerrorBlades]

I export the model without any issues, but once its rigged and skinned the ingame variant seams to explode in to a bunch of black lines.
And if I try and export the model with the animation I get a "Could not reach pose on root translate, rotate." any help on that would be wonderful as the net doesn't seam to shine any light on the situation :S.

if you import your model into the game with a skeleton and have no animations set up you will have that problem. Not sure about the other problem since I don't use maya.
