Are you trying to run a visualization from a view like "Top" or "Front"? DIVA has trouble running images from "parallel" projection views. Look at your Properties window and see what it says next to "Projection". It should say "perspective".Try using a perspective view and run the image metric. That may be one problem.
It also looks like your geometry is not exporting properly. Make sure you have your geometry on, unlocked and materials assigned. If you want to upload your Rhino model, I can look at it and see if I see any other problems.
