I'm stuck in Okumura's palace

Everything was ok until now, i am getting stuck at okumura palace, just after the first boss fight. When i go down the elevator to the second area the game is still working, there is sound and everything is moving but it looks like it is still in loading mode since the character can not move and HP/SP stats of the characters don't appear. I tried using cheat engine just like people where using with the battle crash problem but without success, I'm not using any patches. 

Please help, I don't want all those hours of gameplay to go to waste.
