Nunchuck Not Working

I bought a wiichuck adapter so that I could read the accelerometers off of the nintendo wii nunchuck. I put it together and I ran the example code and wiichuck library from Arduino Playground - WiiChuckClass (the one that just outputs the readings to the serial monitor). I compiled it and uploaded it to my board successfully but when I run it I don't get any output on the serial monitor. I have the baud rate set to 115200 like it says but I still don't see anything. The weird thing is that when the nunchuck isn't plugged in I get readings (although they aren't right) but when the nunchuck is plugged in I don't see anything. I would really like to be able to read data off my nunchuck so any help is appreciated. Thanks in advance.
