Also make sure you have the correct kinect sdk.
At the time of competition, the kinect server required "Microsoft Kinect 1.0 Beta2 SDK". However the latest version is 1.5. I believe that our team had installed the wrong version at first...
It looks like the installer hasn't been updated since January, so you probably use the Beta2 SDK. Available
here.

Hope this helps.
