Help fixing this error, never encountered this before

[Ch1156]

Ok so in my program i have all my headers in main, and I have my constructors in seperate files and for some reason it keeps telling me this

error: expected initializer before 'Game'|
||=== Build finished: 1 errors, 0 warnings (0 minutes, 0 seconds) ===|

Game is the constructor in its own .h file and it keeps saying that, why does it do that? why does the order matter? i never seen that before, i would have never thought that to be a problem, now here are my headers

#include <iostream>
#include <string>
#include <vector>
#include <limits>
#include <fstream>
#include <windows.h>
#include "Pet_Class.h"
#include "Player_Class.h"
#include "Game_Class.h"
#include "Prototypes.h"
#include "GameClass_Constructor.h"
#include "PlayerClass_Constructor.h"
#include "PetClass_Constructor.h"


My code is too big for this post so if you need to see it then let me know and ill put it up on pastebin or something.

A shot in the dark: There's a semicolon or some other punctuation missing just before the constructor declaration.

oh ok i did this

#ifndef GAMECLASS_CONSTRUCTOR_H_INCLUDED
#define GAMECLASS_CONSTRUCTOR_H_INCLUDED

;
Game::Game(bool ISFIRSTSTARTUP): isFirstStartup(ISFIRSTSTARTUP)
{

}

Game::~Game()
{

}

#endif // GAMECLASS_CONSTRUCTOR_H_INCLUDED

is that what im supposed to do?
