dslrdashboard.info

I've just purchased this app so I don't know if I'm doing something wrong. The D7200 connects to the Nexus without a problem and the Nikon app works fine but all I get on dslrdashboard is a black screen with all the usual buttons. Could someone help me please?

I'm having much the same problem with my D 7200. Nikon's app works fine but I only get a black screen. I have only just purchased the software.
