Can't Sculpt

I played with zbrush when I first got it a couple years ago.
I got the 4R5 upgrade and just started trying to sculpt and nothing happens.
I can scale change color and move my model around the screen but can not sculpt on it.
What am I missing?:cry:

go into edit mode (t)

Exit edit mode, and clear your canvas with ctrl+n. Make sure that your RGB and Z intensity are set to 100, and then redraw your tool and enter edit mode again (anything less than 100 will let you see the tool, change its color, and move your view around the object, but would prevent you from sculpting).

I’ve tryed all of that with no luck.
I can scale it I can move it I can change it’s color but I can not sculpt it.
I’m wandering if something is corrupted.:cry:

Is this an existing tool that you created, or any tool?

It is the same with any tool.

What happens to the model when you try to sculpt directly on it?
