the line 11 is shown below
JLabel SplashLabel = new JLabel(new ImageIcon(ClassLoader.getSystemResource("images/Splash Screen 2.jpg")));
public void run()
	{
		JLabel SplashLabel = new JLabel(new ImageIcon(ClassLoader.getSystemResource("images/Splash Screen 2.jpg")));
		Dimension screen = 	Toolkit.getDefaultToolkit().getScreenSize();

it seems, your application is is not picking up the image file and hence "ClassLoader.getSystemResource("images/Splash Screen 2.jpg")" returns null, which results in that exception.

Did you try ?
   ClassLoader cl = this.getClass().getClassLoader();
   Icon icon  = new ImageIcon(cl.getResource("images/SplashScreen2.jpg"));
