render not recognized

I have two avids using ISIS. One system (vers 8.3.1)has a nitris, the other (vers. 6.3.1) is software only. My avid project is on an ISIS partition. When I render a title on the 6.3.1, the render is not recognized in the project on the nitris station. It comes up unrendered.

What I am I doing wrong?

thanks
