Xenoblade Doesn't Recognize Nunchuck

[cfisher2833]

I am trying to run Xenoblade, but for some reason the game doesn't recognize the nunchuck extension. I am using a keyboard and mouse--is that the problem? Does the game require the use of some type of gamepad or will the keyboard and mouse setup work? I have the nunchuck added as an extension under the emulated wiimote configuration and I've used it in other games with no problems. Any suggestions?
