I have never used the stuff, but as it is approved for use any time, I doubt it changed the surface. It may have built up a layer, reducing ball surface to lane contact, causing your dead reaction. I would touch up the surface with an abrasive pad to see if that brings back the reaction. Then adjust surface to what you want after you see it the reaction comes back. I thought that stuff wore off after a few shots, or am I thinking of something else he put out?
