Nikon connected to Aperture 2 but shutter button will not release

[itisgregory]

I am using Nikon D40x and Aperture 2 on Mac OS X. I want to take a photo of a live subject and have it show up in Aperture 2 while I am connected to my computer with a USB cord from my camera. I want to do this so I can see on my 23" screen how the photo looks instead of looking at it on the small camera screen. While my live model is waiting I can know instantly how the photo looks. Many of the pros do this. When I try this the Nikon gives me the message "Connecting". Aperture 2 opens up but Nikon will not let me depress the shutter button. Any suggestions??

You need Nikon Camera Control Pro 2 to do that. Your D40 doesn't speak Aperture.
