Nikon D7200 files would not be supported in CS5 version.
you can either upgrade to CS6 or CC version to get the newer Camera Raw version or you can install the free DNG converter to convert your raw files to DNG and then access them in Photoshop CS5.
Support for the Nikon D7200 was added in the Camera Raw update 9.0. See: Cameras supported by Camera Raw
In order to use the Camera Raw plug-in 9.0, you have to have Photoshop CS6 or later. See: Camera Raw-compatible Adobe applications

Thank you so much for your assistance. I upgraded to CC and am now trying to figure out how to download/open Bridge.
Bridge no longer installs automatically when you install another application. You simply go to the Creative Cloud desktop app, select the Apps tab, find Bridge on the list, and click the Install button. One it has downloaded and installed, you can launch Bridge either from the Creative Cloud desktop app or from your computer (the Applications folder on Mac or search in the Start menu on Windows).
