The constructor "Minim(Minim)" does not exist??

Hello, This is the first time that I have to work with the Minim Library so I just started with a simple sketch to play a wav file. However, even this simple sketch gives me errors?! This is my skecth:

import ddf.minim.*;
//import ddf.minim.analysis.*;
//import ddf.minim.effects.*;
//import ddf.minim.signals.*;
//import ddf.minim.spi.*;
//import ddf.minim.ugens.*;
Minim minim;
//AudioPlayer player;
//AudioInput input;
AudioPlayer song;

void setup(){

  size(100, 100);
  minim = new Minim(this);
  //player = minim.loadFile("song.mp3");
  //input = minim.getLineIn();
  song=minim.loadFile("californication.wav");
  song.play();

}

void draw(){
  background(0);
}

I get 2 errors:

• The constructor "Minim(Minim)" does not exist
• The funtion "loadFile(String)" does not exist

Can someone please help me? :D :D

This is the example code I used:

import ddf.minim.*;

Minim minim;
AudioPlayer song;

void setup(){
  size(100, 100);
   minim = new Minim(this);
   // this loads mysong.wav from the data folder
  song = minim.loadFile("mysong.wav");
  song.play();
}

void draw(){
  background(0);
}
