i get the feeling you recently acquired this camera? I vote for going to a repair person/dealer and letting them look at it -- any cost is an investment in sanity as well as good equipment. If someone very very familiar with the camera says "all you need is this little tool," and shows you how it works, and it does, then buy the tool and send them a thank-you card. While there also buy a pro-pack of film. That is how they make their money.
