Does not work to change color in Sony Vegas Pro 13

Whenever I try to change i color in Sony Vegas pro 13, nothing happens, I have tried to many different Video Fx settings. The only thing who change is that it comes up a little black bar like this:

I have followed steps on youtube when I try to change color on the clips, so I am doing it right!
Does anyone know how how to fix the problem, or things i can try?
Edit: Does not work with green screen either.
