I'm attempting to use the new rendering tools in Revit 2009 for the first time , but I can't even open the render dialog without Revit instantly having a fatal error. This is on an upgraded project as well as a brand new, empty project as a test. Another computer in the office works fine. I've tried OpenGL both on and off.

My computer specs:
Revit 2009 (Web Update 1)
Windows XP Pro (version 2002, Service Pack 3)
Intel Core 2 6400 @ 2.13GHz
2GB RAM
ATI FireGL V3400 (driver - 8.223.0.0, 2/7/2006)

I have also previously upgraded the videocard driver to the latest version because of poor graphic performance. I rolled it back, however, as it caused other visual problems in Revit.

Any ideas?
