JPCSP error when enabling "disable VBO"

[apolloooo]

hi,

i just recently switched PC and copy / pasted my JPCSP from my old PC, but in my new PC it won't work if i enabled "disable VBO" and showed this error:

if i don't check the "disable VBO" , it's playable but the screen is flickering weirdly:




i dunno if it's related to VBO, but i've tried multiple setting and it still like that. it wasn't like that in my old PC

my specs are :
Win 7 - 64 bit
Nvidia GeForce 640m
Intel i7 2.3 Ghz
Ram 4 gb DDR3

my enabled video setting:
only GE graphics
use vertex cache
use shader
use geometry shader
disable UBO
enable VAO
enable saving GE screen to texture

FYI, my NVIDIA drivers are up-to date and i'm sure of it.

thanks in advance
