I know that this is a common problem (the error message anyway) but I haven't found anything that describes the exact problem I'm having. When i try to take photos i hear a strange shutter sound and i get the message 'Error Press shutter release button again'. When i remove the lens i can see that the mirror is raised and the shutter is closed, covering the sensor. When i press the button again the mirror lowers and the error message goes away until i try to take another photo. I've tried opening the bottom and moving the red gear and a touch of WD-40 but nothing changed. The gear seems to be moving just fine. The camera hasn't been used that much either.
