saitek x52 pro - adjusting handle screw is jammed

Hi

I have just bought through Amazon a new Saitek X52 Pro Flight control system.

So far so good..but i wanted to adjust the handle height using the metal screw at the front of the joystick.

But alas.. the metal screw is stuck and move very short spin.

So i used a plier to open it in anti clockwise direction to open it but now it moves freely and the screw wont open.

Has anyone encountered a problem like that or have a soluition?

I'm affraid i wont be able to send it to a fix cause i live outside USA.

Thanks
