Hmm no luck .. when I bake the AO (Ambient Occlusion) to texture all i get is a black map

.. I made sure there was no overlaying textures and set the environment background color was set white . Global lighting level to zero.
In material slot .. gave the object a white diffuse color and added the Ambient occlusion shader to the reflection slot with a sampling of 16.
Then did a render to texture, told max to use existing unwrap, a complete map to be rendered into the diffuse slot, size of 512, output into source and then render .. but all i get is a black map .. can anyone help ? Thanks in advance
