SGP stops with Nikon D5500 dslr!

Hi Guys
First try of SGPro. Installed latest version and just ran it with my Nikon D5500 dslr, created a test directory, created a test user profile no other equipment connected,, set the Nikon for a run of 1- 1x1 1second second shot and prog crashed each time I ran it. Pc is Windows 10 64 bit.
