Example Errors

Here is a example that doesn't work:

From the Reference:
Example

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);

void setup()
{
lcd.print("hello, world!");
}

void loop() {}

That should be corrected to:
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

Then will the reference work with the tutorial, http://arduino.cc/en/Tutorial/LiquidCrystal.

But when I tried to correct it I got a :
Insufficient privileges to perform action.
