Mental Ray Renderer creates solid black images

[Kevin342]

We've been using the default Scanline renderer up to now, with pretty good results.

But when I tried the Mental Ray Renderer (no GI, high) all I get is a solid black frame with the default settings.

Last year we had no problems using the default Mental Ray settings in 3ds Max 9.
