I've recently had a problem with the button for topspin shot not working in the middle of a rally. I would hit a non-acceleration shot, and it would be fine, then the next non acceleration shot, my player doesnt hit the ball... It's almost as though the player doesnt recognize the button being pressed. I've tested out the button outside of TE, and it works fine- there is nothing wrong with it. Only malfunctions when I'm playing TE. Any suggestions? Thanks.
