Solved Right-clicking sign doesn't work after restarting server

I'm making a plugin that uses signs for several actions. When I place them and right-click them, they work perfectly, but, whenever I restart the server they stop working. What's up with that?
Some code:

Code:java

        @EventHandler
        public void onSignInteract(PlayerInteractEvent e){
            if (e.getClickedBlock() != null){
            Player p = e.getPlayer();
                    if (e.getClickedBlock().getType().equals(Material.WALL_SIGN) || e.getClickedBlock().getType().equals(Material.SIGN_POST)){
                        Sign sign = (Sign) e.getClickedBlock().getState();
                        //Join Sign
                        if (sign.getLine(1) == "Click to Join" && sign.getLine(2) == "the game!"){
                            pl.sendMsg("", "Joining game", p, 1);
                            //TODO Add game joining
                    }
            }
            }
        }

Use .equals() instead of == for strings.

 

Thanks! Worked like a charm.
