In order for your webcam to work on a Flash Player application you will need to ensure that your webcam has been correctly installed on to your operating system. If you have done that and your webcam does not connect when you have selected "Allow" 1 from the security window then you will need to try the following instructions.
If you have selected "Deny" for access while at the loading of the application and want to set it to "Allow" you can do so without restarting the application. In "Settings..." select the Privacy Tab 5 icon and click on the "Allow" option (radio) button and then "Close".
