Could use Help with adding a XC21B to a X-10 wireless 3 camera system

[LOOKnonUbAbYCAke]

I already have the Vanguard X-10- 3 Camera system running on a Windows Vista program Computer, with 2 of the color camera's with the pan & tilt, and a B/W low light camera. Running it as a wireless system with the little VR36A video receiver with no audio.
Then I purchased one of the XC21B Camera's which actually comes with the VK77A Vanguard Video Camera System. I was using the CR14A remote to controll my first 3 camera's. However I like the CR15A a little better that came with the 4TH camera I am needing help getting added to the system. I am wondering how I add the XC21B camera to the 3 camera system I already have? I tried the normal going to the vanguard options screen and adding the camera, but it doesn't seem to be doing anything. So I'm not sure what I am doing wrong. I have all my Camera's and remote along with the TM751 and the little transceiver all set on Channel B and each camera on its own number and they all work fine. I just can't seem to get the new camera working. Thank you for any help you might be able to give.

I am having a problem getting my new XC21B to work. I already have 2 of the x-10 wireless color cameras and a B/W low light camera working fine on my computer using Windows Vista, but I am having quite a struggle getting the XC21B added.
I am not sure what I am doing wrong. How can I tell if the camera even works? I know how to add a camera in the Vanguards options area but nothing seems to be happening after adding the XC21B. Could I get a helping hand please.
Thank you so much for your time.
