I don't think Dance Central Spotlight is scoring me correctly. What do I do?
First, make sure you're being tracked by the camera by looking in the small blue or pink square in the top right or top left of the screen. You should be able to see yourself! If you're not there, raise your hand to let the game know you'd like to play. You can also make sure there isn't anything blocking your sweet moves from view, like a coffee table or a pet; if so, move obstacles out of the way so the Kinect camera can clearly see you.
If you're already being tracked, try calibrating your system. You can check or adjust your calibration settings by going to "Settings" from the Main Menu of the game.
