I have a "built in" web cam, which until today activated when I click on the Dell Webcam Central, showing a live video of me. I now get a message across the Webcam Central image informing me to "Please plug in a supported device". I reinstalled the Webcam Central device software for the installation CD that came with the computer, but that did not affect this message. I have looked everywhere, including Device Management, for a way to activate the computer's webcam. Any suggestions where it is? Thanks.
