Camera preventing correct rotation of player to face mouse

Question

I am currently working on a 2d game and I want the player to be able to move around the world freely and always "face/look at" the mouse. To implement this I made a Camera which translates everything in relation to the player:

x = (player.getX()+(player.getWidth()/2)) - game.getWidth()/2;
y = (player.getY()+(player.getHeight()/2)) - game.getHeight()/2;

g2d.translate(-camX, -camY);
//render everything(including player)
g2d.translate(camX, camY);

then when rendering the player i calculate the rotation:

g2d.rotate(Math.atan2(playerCenterY - mouseY, playerCenterX - mouseX) - Math.PI / 2 , playerCenterX , playerCenterY );
//draw player
g2d.rotate(-Math.atan2(playerCenterY - mouseY, playerCenterX - mouseX) - Math.PI / 2 , playerCenterX , playerCenterY );

This works perfectly but once the player has moved (causing the camera to move) it no longer works and I have no idea why. Any thoughts would be greatly appreciated.
