This error is normally indicative of a issue with the shutter wheel, or shutter gear. It could be broken, jammed, or the motor drive could be bad. The gear can normally be access via the bottom of the camera; it can then be lubricated and rotated a few times to prevent jamming. If it's broken, you'll have to replace the gear. If the motor is bad, you can test it or its connections and replace as necessary. Click [[Nikon D3000 Troubleshooting|here]] for more information on your error.
