Wire.requestFrom() not working with nunchuk

I'm attempting to connect a Wii Nunchuk to my arduino and it's getting caught up in the functions Wire.requestFrom(0x52, 6) and Wire.endTransmission(). If it starts either of these, it never reaches anything after. As far as I can tell I have all of the wiring hooked up properly (currently I've only got the nunchuk connected), and other people have gotten the nunchuks to work using the same code (I've tried both the stuff from http://github.com/lgeek/Arduino-Wii-Nunchuk and from http://www.windmeadow.com/node/42 with no success. Currently I'm trying the stuff from lgeek).
