Legend of zelda wind waker black screen freeze

[daanvandam]

Hello i was wondering if anyone could help me with my problem. This is what happend: I was completing forsaken fortress and just got the sword back and i beat the little mobin guy but when i entered the door it was black screen Sigh...(im bad at sneaking so this took me ages) after finnaly getting up again because i had to do everything over the black screen wasn't here anymore YAY! But it froze right after you see the king of read lions next to you (no time to save) i gave up and went on the forums. the problem is it doesn't freeze at a certain point it just freezes whenever it feels like it,
