Kingdom Hearts: Birth by Sleep - US - ULUS10505

Hi Guys!
When I try to run this game, it runs very smooth at first
opening title, main menu, etc in 60fps
but after the second cutscene (the white haired man that say "This world is too small blablabla")
the fps drop from 60fps to 1-2fps and stuck at loading screen
although the music is running normally
I am using the latest build

my specs :
AMD Athlon II X2 245
Radeon HD5570
4gb DDR2 RAM
W7 32 bit
----------------------------------------------------------------------------------------EDIT-------------------------------------------------------------------
the game works now
I enable "Use Software Rendering" option
but the game is very very laggy, unplayable
