DEMO code not working! #5

Hello!
I have an arduino uno and a 3.6 inch TFT LCD ili9327 controller chip. I downloaded the UTFT.zip posted and I wanted to verify if the LCD works as you described. The only change that I made in your code is : UTFT myGLCD(ILI9327,A5,A4,A3,A2); as you cand see in the next code that I just copy
// UTFT_Demo_400x240 (C)2014 Henning Karlsen
// web: http://www.henningkarlsen.com/electronics
//
// This program is a demo of how to use most of the functions
// of the library with a supported display modules.
//
// This demo was made for modules with a screen resolution
// of 400x240 pixels.
//
// This program requires the UTFT library.
//

include <UTFT.h>

// Declare which fonts we will be using
extern uint8_t SmallFont[];

// Set the pins to the correct ones for your development shield
// ------------------------------------------------------------
// Arduino Uno / 2009:

// Standard Arduino Uno/2009 shield : ,A5,A4,A3,A2
// DisplayModule Arduino Uno TFT shield : ,A5,A4,A3,A2
//
// Arduino Mega:

// CTE TFT LCD/SD Shield for Arduino Mega : ,38,39,40,41

// Remember to change the model parameter to suit your display module!
