Can't start nodes

[bzreinhardt]

When I run $ roslaunch k2_client kinect2Client.launch (after running rosmake and adding the folder to my ros path)

I get:
... logging to /home/ben/.ros/log/9136685e-5d42-11e4-8e16-90fba646d152/roslaunch-ben-DX4831-31694.log

I'm not sure why it can't find the node files, while still finding the launch file.
