If Player is failing to start, it's because one of the drivers is 
failing to start, probably returning -1 from MainSetup or calling 
SetError(-1) in the constructor.  You can modify the driver to be more 
lenient in the face of an error and keep retrying a connection, instead 
of issuing an error.  You can also try to start several instances of 
Player, one for each different robot, so you don't have to make sure all 
of the robots are online for everything to work.
