I used to have Sony Vegas Pro 10, many moons ago. I used to use Color Corrector (secondary) all the time with no problem. I recently purchased Vegas Movie Studio, and Color Corrector (secondary) is not working! I add it to a clip, go to custom, and click the eye dropper next to "select effect range". I used to just click on a color in my preview and it would select any object in that color. Now, when I click a color, nothing happens! If I click "show mask" its all black. I tried dragging the eye dropper over a color instead, but still doesn't work. Once in a while that will result in multiple colors being selected or just white being selected. I never had a problem with this in Sony Vegas Pro.. How do I fix it?! Of course VEGAS has no customer support so I am relying on someone to please answer me here!!!!
