Configuration always return nulls

Hello,
maybe I misused the Configuration class, but I'm only getting nulls:

Code:

public void loadSettings(File dataPath) {
        System.out.println("FILE: " + new File(dataPath, "qukkiz.yml"));
        Configuration config = new Configuration(new File(dataPath, "qukkiz.yml"));
        ConfigurationNode rewardsNode = config.getNode("rewards");

        System.out.println("rewards: " + rewardsNode);
        this.pointsReward = RewardSettings.create(new PointsRewardSettings(), rewardsNode);
        this.itemsReward = RewardSettings.create(new ItemsRewardSettings(), rewardsNode);
        this.coinsReward = RewardSettings.create(new CoinsRewardSettings(), rewardsNode);
        this.questionfiles = convert(config.getStringList("questions.files", new ArrayList<String>(0)), dataPath);
        this.questionsDelay = config.getInt("questions.delay", 5);
        ConfigurationNode hintsNode = config.getNode("questions.hints");
        System.out.println("questions.hints: " + hintsNode);
        if (hintsNode != null) {
            this.hintCount = hintsNode.getInt("count", 3);
            this.hintDelay = hintsNode.getInt("delay", 15);
        } else {
            this.hintCount = 3;
            this.hintDelay = 15;
        }
        this.intHinter = HinterSettings.create(new IntHinterSettings(), hintsNode);
        this.wordHinter = HinterSettings.create(new WordHinterSettings(), hintsNode);
        this.choiceHinter = HinterSettings.create(new ChoiceHinterSettings(), hintsNode);
        System.out.println("ranking.database: " + config.getString("ranking.database"));
        this.database = new File(dataPath, config.getString("ranking.database", "qukkiz.db"));
    }

Now I got this in my console:

Code:

13:32:22 [INFO] FILE: plugins/Qukkiz/qukkiz.yml
13:32:22 [INFO] rewards: null
13:32:22 [INFO] questions.hints: null
13:32:22 [INFO] ranking.database: null

And this is my qukkiz.yml file:

Code:

xzise@fabian-m:~/Programme/Minecraft/RB$ cat plugins/Qukkiz/qukkiz.yml
rewards:
  points:
    start: 10
    decrease: 2
  items:
    list: [87, 88, 89, 12, 21]
  coins:
    start: 10
    decrease: 3
questions:
  files:
    - 'questions/german.txt'
    - 'questions/scramble.txt'
  hints:
    count: 3
    delay: 15
    word:
      letters-per-hint: 8
    int:
      start: 200
      decrease: 4
  delay: 5
ranking:
  database: 'trivia.db'

Now what did I wrong?

Thank you alot for your help. I missed to load the file. So if anyone have similar problems add following line after the constructor.

Code:

config.load()
