I have just bought a new laptop, it has windows 8, the webcam is built in. With the skype app for windows 8, my webcam doesn't work, and I can't see the person I'm talking to. I've deleted the app and installed it again(plenty of times), the webcam still doesn't work. So I downloaded the skype app for windows 7/xp/vista, and my webcam still doesn't work. We can hear eachother, but we just can't see eachother. There are no updates for the app, because I've just downloaded the app again. What can I do?
