DueGui demo not working for 3.2¨ TFT LCD touch shield


I'm trying to get the DueGui demo2 to work with my itead studio 3.2¨ TFT LCD touch shield but i'm failing....
I'm using this initialization:
DUEGUI DueGUI(ITDB32S,38,39,40,41);

but i'm not getting anything in the display!

When I try the example in the "UTFT\examples\Arduino (ARM)\UTFT_Demo_320x240" with the same display type I can get this example to work so I guess I'm missing some other changes that I need to make to the DueGui demo2 in order to get it working but I have no idea what it could be...

Any ideas/sugestions?

I have a similar issue. I have a 3.2 TFT 240x400 from elechouse. When I add the following to demo2

DUEGUI DueGUI(HX8352A,22,23,31,33);

I can compile demo2, however nothing shows on the display, after upload. Any help would be greatly appreciated. I can compile other UTFT sketches and use the touch screen as well.
