Allegro 5 problems

Theodor Purcaru (3)
*NOTE THIS IS IN VC2010;
I have been recently trying my luck with allegro 5 and, although simple code works, even drawing and moving primitives, more complex things, or even loading fonts, give me a really annoying error when I debug. I researched the error and it said it was due to a pointer pointing towards something unexistant or NULL but I can't figure it out.
This is the code:

#include <allegro5\allegro.h>
#include <allegro5\allegro_native_dialog.h>
#include <allegro5\allegro_ttf.h>
#include <allegro5\allegro_font.h>

#define screenWidth 800
#define screenHeight 600
int main()
{
	ALLEGRO_DISPLAY * display;

	const float FPS = 60.0;

	if (!al_init())
	{
		al_show_native_message_box(NULL, "Error", NULL, "Could not initialize Whack-a-Squirrel properly", NULL, NULL);
	    
	}

	al_set_new_display_flags(ALLEGRO_WINDOWED);
	display = al_create_display(screenWidth, screenHeight);
	al_set_window_position (display, 200, 200);
	al_set_window_title (display, "Whack-a-Squirrel");

	if (!display)
	{
		al_show_native_message_box(NULL, "Error", NULL, "Failed to initialize the game", NULL, NULL);
		return -1;
	}

	al_init_font_addon();
	al_init_ttf_addon();

	ALLEGRO_FONT  *font = al_load_font("Orbitron Black.ttf", 36, NULL);
	al_draw_text(font, al_map_rgb(44, 117, 255), screenWidth / 2, screenHeight / 2, ALLEGRO_ALIGN_CENTRE, " Test Screen ");

	
	al_flip_display();
	al_rest(10.0);
	al_destroy_font(font);
	al_destroy_display(display);
	return 0;
}


I recieve this error :

 
 
Unhandled exception at 0x0fb2c11f in ProjectTest.exe: 0xC0000005: Access violation reading location 0x00000008.


And I can only break, continue at which point I keep pressing for ever or ignore which is greyed out.
