FFI PSP game crashes in Whisperwind Cove

Anyone else's PSP crash and shut off at all during this game? I am stuck in level 14 of the Whisperwind Cove dungeon, and every time I try to use the stairs to go to the next level, my screen goes black, and the PSP shuts right off a few seconds later. I've tried it at least 4 or 5 times now. I haven't had any other problems with the game until this point. I'm wondering if this is a glitch at this specific point, or if there might be something wrong with my game.

My only option was to let myself die (which is quite hard at this point since the enemies are weak and you can't attack your own team members!) to get out of the dungeon. I'm not sure if I should re-enter and try the dungeon again.

You could try returning the game, pointing out that it's crashing in the exact same spot.
