Script Error Giratina Boss Battle! PLZ HELP!

Hi, I’m a huge fan of this game and I just beat Forgotten One Evy? I think. Anyway whenever I tried to battle Giratina it showed up with this… PLZ REPLY QUICKLY CAUSE I WANT TO PLAY THIS AMAZING GAME AGAIN!

Have you updated to latest patch, 1.2.3?

Never mind. I did some research and turns out I was missing some files, so I re downloaded the game. Thx for replying though Sleepy!
