question about animation in the game engine

i have been trying to get an object(a sphere) to orbit the object that i contoll with the arrow keys in the game engine(a cube) . i cannot get this to happen. everything that ive read says that i should choose the play option in the actuators, but it just isnt there in blender 2.43
i think ive created an animation correctly by parenting the sphere to a bezier circle and then saying its a path. it plays when i hit ctrl a but it just wont work in the game engine.
if someone can point me to a great walkthough about this or just tell me what to i would be so happy!

You should probably ask in the Game Engine forum. Maybe the moderator will move it for you.
