Need urgent help from Maya users about animation

I have two problems about exporting animation from Maya 7 to egg. Here are the files:
The problem of the new.egg file is that although the animation works well in Maya, the character’s leg movement is distorted after converting to egg file (use pview to view the egg file). Furthermore, if you put the character into a scene, when the animation starts to play, the character will be wierdly shifted downward with distorted leg animation. No error message during the loading.
dreamWalk file has a different problem - the character doesn’t move at all in pview. No error message again.
I am very new to Maya and Panda3D. Can anyone help me about it?
