Cannot load PAL games on US machine.

I have a US machine with Crystal 1.1 chip installed,
i'm trying to run a PAL game but it wont load no matter what i'm doing,
it's loading the Intro and the intro movies, but it wont load the game itself
(original copy of worms world party), it's loading the demos i've recived with them without any problem but will simple not load the pal game...

i have 2 machines now (i ordered one after the other) both slim, both with Fix for the laser, one with Matrix and one with Crystal and both of them wont load the games....


any suggestions before i'm freaking out ?

Anyone else has any idea how to solve this ?!
i have 2 Consoles wont play ANY of my PAL games..
no matter what..
