Trouble Batch Rendering

For some unknown and frustrating reason my brother's version of Maya will not allow him to render models that are too complicated. When a render is complete it is totally blank. So we have decided to render using my laptop, as transporting .mb files on to my version of Maya seem to be renderable and there are no problems.

I am attempting to render a time lapse scene where the sun Arch's from East to West over the hotel model. However when I batch render the physical sky disappears. I learnt that I needed to reconnect the physical sky attribute to the newly created camera. Hopefully when I re-render the physical sky shader will be present.
