For the 1st brush in the basic set, my brush controls look just like the panel in your email. Do you see the little triangle to the left of the top "Control" work? With the ! in it? That means that function is not supported. And sure enough, when I try tilting the pen while drawing, retouching or whatever, there is no change in diameter. Same "non-result" if I try to use pen tilt on any of the other brushes or brush parameters.
