Enum class is not recognized by some other class

I'm having a hard time with "enum class". I understand it is a C++11 feature and also I've read about the differences between enum class and plain enums.

I have declared a "Token" enum class:

Token.h

enum class Token
{
    EMPTY,
    BLACK,
    WHITE
};

and a "Game" class, that uses the Token class:

Game.h

#include <Board.h>
#include <Token.h>

class Game
{
public:
    Game();
    ~Game();
    ...
private:
    Board board;
    Token turn;
    bool endGame;
    Token winner;
};

Game.cpp

Game::Game()
{
    Board board(6,7); //Create board with 6*7 size
    board.reset(); //Reset the board
    turn=Token::WHITE; //First turn for WHITE player
    endGame=false;
    winner=Token::EMPTY;
}
...

The compiler gives me the following error for the constructor for Game:

In constructor Game::Game() error: 'Token' is not a class or namespace

The same error happens for any use of a Token class variable inside the Game class.

If I transform the enum class in just an enum and remove the "Token::" references before the use of the enum values, it works perfectly. What is happening?

P.D.- FYI, I'm new in C++ programming, but I have experience with PASCAL, C and in OOP with Java.
