Can some one explain these errors?

I have tried rendering this scene numerous times in batch render with no success. I rendered out one frame and here are the errors I recieved how do I go about fixing them?

All help welcome with an advanced thank you.

Also do you have to register mental ray? I thought it was a plug-in that came with Maya and once you registered Maya it automatically registered Mental Ray.

Thanks...
