Creating Space Invaders - Can't Stop 'Game Over' Screen coming up at start

Programming Questions
I have a almost finished Space Invaders Game. But when the game starts, it thinks that Game Over has Occurred.
I'm getting no error code. Also any slight tweek's are welcomed if they are noted.
If you can help, thank you very much.
Sorry about the Long code, but Invader1Bullet class is basically repeated in the corresponding numbers.
Code:
SpaceShip spaceship;
bullet bullet;
Invader invader1;
Invader invader2;
Invader invader3;
Invader invader4;
Invader invader5;
Invader invader6;
Invader invader7;
Invader invader8;
Inv1Bullet inv1bullet;
