Animation importation from maya problem

Ok so I have made a model within maya which I have animated, however when I try and import it into unity it does not move correctly.

I have a video of the animation here : Animation of the drone - Maya imported into unity - YouTube

however when I import it into the unity the model stays in the T position and the shoulders rotate, for the stab animation the arms do no bend. I cannot use the 2011.3 fbx importer because there is not a version for 64 2012 maya.

Does anyone know how I can go about fixing this ? I have tried selecting the bake animations option in unity aswell, doesn’t seem to work.

here is a video of the issue
