Pokemon X/Y Crash

So i got a copy of Pokemon Y, and it played great.. until the ice cavern around the 6th=7th gym. i went into battle, and i made my lucario use Aura Sphere, The animation played, halfway through the volume stopped and then an error screen popped up, i thought this was a one time thing, but everytime the animation would play for ANY MOVE from ANY POKEMON it would crash, so i turned off the battle effects and continued the story, i eventually caught yveltal, and its moves work fine, but my fennekin or lucario or anything else cant make a move, i dont mind the no battle effects, but at the 8th gym, the animation that plays when you beat wulfric crashes the game too, keeping me from progressing through the story, i tried updating the game and repairing the software, but nothing works, is anyone else having this problem? and is there a solution that doesnt involve restarting my game? Please And Thank You -Light
