Rendering crashes unless setting viewport to IRay beforehand [solved]

If I try to render with any settings it will crash just after completion of the render, tried turning off filtering and such but it didn't help.  It was rendering just fine yesterday.  I started screenshoting the viewport in IRay to get around the issue for now so I could storyboard and then decided to try rendering again for the heck of it.  The rendering succeeded, so I turned off IRay in the viewport without changing anything else and it went back to crashing again.  Does anyone have any idea what is causing this?

Was a driver update installed before the crashing started? What are your system specifications, and what security software are you running?

To anyone in the future who ends up finding this and has the same problem: It is a problem with conflicting IRay settings between merged files, you need to delete the Environment and Tonemapper Options objects from the scene before you save them if you intend on merging them in to a different scene which also has them.
