Gear connections cause issues generating animations

I am using Creo Parametric Release 4.0 and DatecodeM150

I am using the Animation Application to create animations and videos of an assembly in motion using snapshots. I can generate animations using snapshots until I create gear connections in the mechanism application (there are gear to gear connections and worm gear connections). I can drag the components around with some lag, but when I try to generate an animation those components affected by the gear connections do not move.
