Dell Webcam Center Video lagging and slow

Hello, I have no idea what has happened to my video on the Dell Webcam Center but it seems to have slowed down, even in the voice aspect you can hear it is slow and the video is blurry as if any single movement were too fast for the video to capture.  I have checked and it says it is recording at 30 frames a minute but I cannot seem to find a "reset" button to get back to the original settings for the computer.  Thank you for any help you may be able to provide.
