Maya Unity 3 and animations?????

What has happand to Unity 3.1 and maya animations. Things that worked in U 2.6 do not work any more in U 3.1
I was able to put my maya *.mb files in a asset folder , select bake animation in the importer and the animations worked like a charm, now when I do the same in U 3 the model get squished but straightens out when a animation is played.



(left: no animation playing the model is squished??, right: animation is playing and the model looks OK )

If I take a *.mb file that I know worked in U 2.6 and put in a U 3.1 its squished.

Is't the FBX that is spooky??? Or Unity 3.1??

Using maya 2009.

Help Please!
