Prince of Persia

Have anyone here done Prince of Persia the Sands of Time? I'm having troubles in the lasts parts, I cant finish it :( If you remember it, could you give me a pm or something...

I'm in the part after I got into the Arogus(Or however I spell it, it's the big thing with the sands :o), I trickjumped into the top center of the Arogus and had to swing my dagger in the middle, but then there was a cinima were I didnt trust the girl etc, and the old magician showed up and flew me up from there, then I was in some black place, where there was a cinema conversation with the prince and the girl, then she said a word and the tomb opened, and i entered. Then I got into some wierd place with wierd music, I had to walk for so long and got into wierd place with a small water poll and symbol in middle of it, full of rooms, which when I enter them, I gets up to get out in an other room, but still in the same place...

I want to finish this retarded game, I love it :<
