You won’t be able to get a new CD for your webcam but there are many sites on the internet that will allow you to download the drivers for free. Remember Google is your friend just use the search term “veo advanced webcam driver” and you will find many sites to get the drivers from. Beware of sites that try to install anything on to your computer.
At the bottom of this page there are 3 links for disk images of the drivers and software apparently its only for XP an older but there is a way to do it in Vista just read the directions.
