I don't think that will work since I don't have a Navida driver. But I appreciate any ideas that you may have.
Do you mean NVIDIA? By chance are you logged on to 360 through InfraWorks?
I finally did get it working. I had an update come across for my video card driver and once I installed that, the software started working. Seems to be centered around the video card drivers. Good Luck.
I have found that I get this error within Infraworks when I check the "Use corridor regions instead of top surface" box under the IMX Road options. The only way I could get back into Infraworks was to recreate the entire model.
