Dissidia 012: Duodecim Final Fantasy

[Diplocephalus]

I've been playing the game perfectly, just some random crashes that never really hurted on story mode since I could restart the game and the game never crashed again on the same part allowing me to pass. But on the epilogue of the story on 013 when entering the last battle of the first dungeon it always crashes, I can't get past that part and is almost at the end, I'm so frustrated pls help
