hey, i have an Lenovo g470 laptop with windows 7 Home Basic, Service pack 1, 64 bits and the webcam wont work. when i start up cyberlink youcam, it says: "Warning, No webcam detected. Try plugging in a webcam into your computer now. If you are using an integrated camera, make sure that it is turned on". It worked when i first got my computer for a few months, then it stopped. I havent used it for a few months because of this problem. Please help me! Any help is appreciated, thanks!
