That looks like you are using a VERY old version of NetworkTables. What screensteps page did you find that on?
The newest version can be found at
http://first.wpi.edu/FRC/roborio/mav....5-desktop.jar. Try using that jar instead, as that has been tested to work with the newest robot version of NetworkTables.
The only thing I'm going to recommend changing is in your Java code, use setTeam(5104) rather then setIPAddress. setTeam has mechanisms built in to help connect easier.
