Mental Ray Problems (2)

I recently ungraded to Maya 8 and went to render a displacement map with mental ray. Went to Window > Render Editors and mental ray should be there but its not. Even when i got to the render settings all it has is the Software, hardware, and vector renders????

I need help soon, finals are here and im screwed without mental ray.

load/autoload Mayatomr.mll with the Plugin Manager
