Check your motor controllers to make sure they are plugged into the correct spots on the Digital Sidecar. If that doesn't help, remember that 2 of the motors must be inverted in Begin.vi for it to work correctly (I generally invert both left motors. If they all function correctly, but the joystick is backwards, then invert the other two instead.) Hover over the Open 4 Motors.vi and you will see 4 green dots (2 on top and 2 on bottom) that reference the inversions.
