Cannot find Symbol for prompter.displayProgress()

I keep getting a "cannot find symbol error". I have checked almost everything I can and still can't figure it out. Here's my code:

Hangman.java:

public class Hangman { public static void main (String []args)

{
    Game game = new Game("Treehouse");
    Prompter prompter = new Prompter(game);
    prompter.displayProgress();
    boolean isHit = prompter.promptForGuess();
    if (isHit)
    {
        System.out.println("we got a hit!!");
    }
    else
    {
        System.out.println("Oops! Missed :(");
    }
    prompter.displayProgress();
}

}

Game.java:

class Game { private String answer; private String hits, misses;

public Game (String answer)
{
    this.answer = answer;
    hits ="";
    misses = "";
}

public boolean applyGuess(char letter)
{
    boolean isHit = answer.indexOf(letter) != -1;
    if (isHit)
    {
        hits += letter;
    }
    else 
    {
        misses += letter;
    }
    return isHit;
}

public String getCurrentProgress()
{
    String progress = "";

    for (char letter : answer.toCharArray())
    {
        char display = '-';
        if (hits.indexOf(letter) != -1)
        {
            display = letter;
        }
        progress += display;
    }
    return progress;
}

}

Prompter.java:

import java.util.Scanner;

class Prompter { //this class will be used for all IO private Game game;

public Prompter(Game game)
{
    this.game = game;
}

public boolean promptForGuess()
{
    Scanner scanner = new Scanner(System.in);
    System.out.print("Enter a letter:       ");
    String guessInput = scanner.nextLine();
    char guess = guessInput.charAt(0);
    return game.applyGuess(guess);
}

public void displayProgress()
{
    System.out.printf("Try to solve :  %s%n", game.getCurrentProgress);
}

}

And here's the error:

Hangman.java:8: error: cannot find symbol prompter.displayProgress(); ^ symbol: method displayProgress() location: variable prompter of type Prompter Hangman.java:18: error: cannot find symbol prompter.displayProgress(); ^ symbol: method displayProgress() location: variable prompter of type Prompter

UPDATE:

Now the error has moved to this line:

error: cannot find symbol System.out.printf("Try to solve: %s%n", game.getCurrentProgress); ^ symbol: variable getCurrentProgress location: variable game of type Game

Ok got it. The I didn't open and close brackets after game.getCurrentProgress

For some reason I can't delete this question so please ignore it.
