Can't Export Animation

I made a character model and tried to export with this u3d plugin.
But when I export it, the model is 0 bytes and has no geometry data, basically no model. Below is what I get in the console window .

Whenever I try to export the model with animation, it fails and the image below is what I get. When I export it WITHOUT animation, it works fine. So what’s wrong?

What’s wrong, and how do I stop/fix it?

Looks like the mesh does not have an armature correctly parented to it. The mesh has weights but it can find the armature to get the vertex location from.

Post the blend.

I’ll try and post it, by my dial-up connection is really bad.

Can someone answer this?
