I'm having some trouble with Uncharted 2. Whenever I come back from a loading screen or load my game, or a cutscene, I automatically equip a grenade, and I can't unequip it until I throw it or fall off of something. Also, I'm unable to scope in on any of the long guns, my input is simply ignored. I'm assuming this is a controller issue, I could be wrong. I've owned this controller and game since 2009, so they aren't in the best shape, but they were fine a week ago. Any ideas?
