Well from what I can see I'm not sure!
What is it you are trying to raytrace and how do you know it hasn't?

The one thing I would say on the settings there is that the Raytrace bounce is too low IMO, I normally have that at 3.
I gotta say I tend not to use the pre defined settings, I use my own and save them!
Try increasing the settings and see if that sorts it, sorry that's the best I can offer there!!

Injustice will be avenged.
