So the sphere is not emitting any light on any objects? Set the plane (or floor object) to static and keep the sphere static and see if it emits light properly. Then you can make the sphere move to test it with the light probes. For the animation, make sure you animate it in the position you want it to move. If you try to move the object after you animated it, it will always revert back to the original position you animated it at when it plays. If you need further help let me know.
