CubeMX 4.3 + IAR ARM 6.7 + STM32F4-DISCO

I have downloaded project for STM32F4-DISCO board ( CubeMX 4.3 ). I can export it to IAR, compile and download into board. But I can't turn on any led on board with standard instruction.
"GPIOG->ODR=..." is working good, but 
"GPIOG->BSRRH=..." or
"GPIOG->BSRRL=..." on next line of project can't change pin level...
I try to download MEMS-example for this board and make some change ( led turn on ) - it works with "GPIO_PORT[Led]->BSRRL" string...

What problem is it?
