Nuitrack_body_tracker process has died


I purchased a nuitrack library for skeleton tracking on ROS.
I tried to run it using the [roslaunch nuitrack_body_tracker nuitrack_body_tracker.launch] command, but it keeps failing.
Other samples, such as nuitrack_gl_sample, work fine and the nuitrack license is active.

My operating system environment is ubuntu 16.04 and I am using Kinect V2 camera.

I need support. Thank you.
