I upgraded my Mac Pro to version 10.6.8 and crashes.
I can not change the configuration of my LFG, or my phoenix. When I try to change crashes.

I reinstalled drivers LFG, but crashes, wanting to change the configuration from imput window

My setup is
Mac Pro 2x2, 66 - 1.1
6GB
ATI X1900 Radeom
LFG 4
Phoenix 2XHDSdi

thanks
