Thank you, thank you very much.

The system always starts in 32-bit mode.

I deleted the settings file, and I started with a blank settings. (I have not uninstalled the cards, I thought to do next if this does not work).
I restarted Catalyst with blank settings and then configure it, everything is back to work as before, I can change resolutions and so from the window of inputs. ! And it does not crash!
Well not everything worked (maybe because of the 10.6.8 update) the case is that the keyboard does not work and I can not redo the patch, all parameters are controlled by DMX and are more than 100 devices to patching.

Any ideas.

thanks
