More Cocoa Programming for Mac OS X: Help With DO

I was reading an going through the chapters on the “Rough Cuts” “More Cocoa Programming for Mac OS X: The Big Nerd Ranch Guide” book on Safari Online. I’m not sure where to ask but I have a question on Chapter 22 “Distributed Objects”.
I was going through the code and had a issue where if the “ChatterD” server was left running and the “Chatter” client is exited and re-launched it will not re-connect to the “ChatterD” server. I just keep getting a exception error. So I decided to run the example code and I get the same result.
