Ghost Of Sparta Iso problem?

I just started the game (downloaded it) and I am already in the level that says "Thera" where there is a big head in a volcano. When I get close to the head, I thought there was going to be a cutscene because the screen went black. But when I waited 5 minutes, it stayed the same. Black. I did reload the save when nothing happened. I tried again 5 times, then nothing. I just wanna ask if anybody encountered a problem like this from the Ruther Rip. If not, then maybe it's my cfw. Which is 5.50 prome 4. By the way, I doubt its my CFW because the rest of the game worked flawlessly except this level.
