Robotis Manipulator Error in roslaunch

edit

I am trying to roslaunch the manipulator_manager.launch file but am getting the following output (the important part):

process[manipulator_manager-1]: started with pid [17993]

I am using ROS Indigo on Ubuntu 14.04. Does anyone have any suggestions on how to solve this error? Any help will be much appreciated.
