I Pad not receiving all Cams???

I just checked out the EarthCam website on my kids desktop computer and was shocked to see that the $7.99 I paid for the APP doesnt include all the Cams??? Why??? Not only is my App not loading properly, now I find out Im not receiving all the Cams??? I want a response please. Why are not all the Cams available?
