Please anyone!!

I just bought the home edition of Boinxtv in the App shop. I managed to change all the settings in the templates ( newsreader) but I can’t get rid of my background. I use my build-in camera. I go to the controls for the chroma keying but I probably do something wrong as I get my video inside the template but with the background of my office wall. Can someone please explain what I should do or how the controls have to be.
Thank you all inadvance.

Jose, thanks for purchasing BoinxTV Home. In order to use the chroma keying, you need to have a uniformly colored background instead of your office. Use a wall painted in green or blue or a cloth in blue or green. There is a tutorial on chroma-keying on http://boinx.com/boinxtv/howtos/ (bottom right).

Let me know if this helped.
