Alrighty so I downloaded forge just fine and it said it was downloaded successful! I checked and forge was installed! But when I clicked play It would load for a split second then take me back to the launcher saying "ERROR Game crashed. An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience. Exit Code:0". It was downloaded correctly I am not sure why it is not working! Anyone have any suggestions!?
