I have the following code for a SpaceInvaders game, and repaint doesn't do anything.

Using System.out.println() for debugging, I have noticed everything works smoothly, but repaint does nothing.

Paint throws an error from the super.graphicsComponent(); if called directly with paint(getGraphics());

public class Launcher extends JFrame{
	
	private JButton nGame;
	private JButton lGame;
	private String dir = "";
	
	public Launcher(){
		super("Space Invaders");
		setLayout(new FlowLayout(FlowLayout.CENTER));
		
		if(isWindows()){
			System.out.println("Windows");
			dir = System.getenv("APPDATA") + "\\.SInvaders\\";
		}
		if(isUnix()){
			System.out.println("Linux/Unix");
			dir = "~/SInvaders/";
		}
		if(isMac()){
			System.out.println("Mac");
			dir = System.getProperty("user.home") + "/Library/Application Support/SInvaders/";
		}
		
		nGame = new JButton("New Game");
		lGame = new JButton("Load Save");
		File sav = new File(dir+"save.sav");
		
		add(nGame);
		add(lGame);
		
		nGame.addActionListener(new HC(false,dir));
		lGame.addActionListener(new HC(true,dir));
		
		if(!sav.exists()){
			lGame.setEnabled(false);
		}
		
	}
	//OS Detection functions, isWindows(), isUnix(), isMac()
	
	private class HC implements ActionListener {
		
		boolean load;
		String dir;
		public GameInit g;
		public GameInit g2;
		
		public HC(boolean load, String dir){
			this.load = load;
			this.dir = dir;
		}
		@Override
		public void actionPerformed(ActionEvent arg0) {
			remove(nGame);
			remove(lGame);
			repaint();
			
			try {
                                //Launch the GameInit
				g = new GameInit(load,dir);
				
                                //make it visible
                                add(g);
				g.setVisible(true);
				g.setFocusable(true);

                                //give it focus
				g.requestFocusInWindow();
				g.requestFocus();

                                //enlarge it to populate the entire JFrame
				g.setSize(400, 600);
				g.repaint();

                                //add key listener to JPanel, passing it the character's X coordinate
				g.addKeyListener(new KL(g.charX));
			} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
			}
		}
		private class KL implements KeyListener{
			private int x;
			public KL(int x){
				this.x = x;
			}
			@Override
			public void keyPressed(KeyEvent e) {
				int code = e.getKeyCode();
				if(code == KeyEvent.VK_LEFT){
					if(this.x > 0){
						this.x -= 10;
						System.out.println(this.x);
						new GameInit(this.x);
						System.out.println("Left");
					}
				}else if(code == KeyEvent.VK_RIGHT){
					if(this.x < 336){
						this.x += 10;
						
						System.out.println("Right");
					}
				}else if(code == KeyEvent.VK_SPACE){
					System.out.println("Fire");
					fire(g.charX);
				}
			}

			@Override
			public void keyReleased(KeyEvent e) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void keyTyped(KeyEvent e) {
				// TODO Auto-generated method stub
				
			}
			public void fire(int x){
				
			}
			
		}
	}
}

Where GameInit is the following:

public class GameInit extends JPanel{
	
	public int points;
	public int lives;
	public Image heart;
	public Image player;
	public boolean imLoad = false;
	public String dir;
	public int charX = 125;
	
	public GameInit(){
	}
	public GameInit(int x){
		this.charX = x;
		repaint();
	}
	public GameInit(boolean load, String dir) throws IOException{
		if(load){
			Scanner p = new Scanner(new FileInputStream(dir+"save.sav"));
			points = Integer.parseInt(p.nextLine());
			lives = Integer.parseInt(p.nextLine());
		}else{
			points = 0;
			lives = 3;
		}
		this.dir = dir;
		loadImages();
	}
	public void loadImages(){
		if((new File(dir+"life.png").exists())){
			heart = new ImageIcon(dir+"life.png").getImage();
		}else{
			System.out.println("No File \"" + dir + "life.png\"");
		}
		if((new File(dir+"char.png").exists())){
			player = new ImageIcon(dir+"char.png").getImage();
		}else{
			System.out.println("No File \"" + dir + "char.png\"");
		}
		
		if(player != null && heart != null)
			imLoad = true;
	}
	public void paint(Graphics g) {
		super.paintComponent(g);
		super.setBackground(Color.BLACK);
		if(g instanceof Graphics2D){
			Graphics2D g2 = (Graphics2D)g;
			
			Font def = new Font("Courier New", Font.BOLD, 16);
			g.setFont(def);
			g.setColor(Color.WHITE);
			g.drawString(Integer.toString(points), 10, 568);
			//g.drawString(Integer.toString(lives), 384, 568);
			if(imLoad){
				for(int x = 374; ((400 - x) / 16) <= lives; x = x - 16){
					g.drawImage(heart, x, 558, null);
				}
				g.drawImage(player, this.charX, 490, null);
			}else{
				System.out.println("Could not acquire 1 or more image(s)");
			}
		}
	}
