Animation not exporting?

Greetings,

I am trying to export my beating heart animation. One mesh, perfectly UV’d. I used clusters to animate it, I tried GeoCaching it and adding that as a clip. nothing…

I also tried blend shapes… nothing

How can i export this animation?
FBX, DAE_FBX, OpenCOLLADA ?

im using the most recent plugins as of 12 / 5 / 2011

… of those three choices, I think OpenCOLLADA does the better job at exporting.
