Cannot add more wiimotes (360) in new super mario brothers

[Exostenza]

I have the 360 wireless receiver and my pads are recognized in Dolphin 2.0 and are easily set up. My problem is when I got o play new super mario brothers and it asks me to add more wiimotes when I go to the screen that asks me to press 1+2 on the wiimotes that I want to add pressing the buttons assigned on the 360 pad does not work. I can play single player fine and all the buttons register in the options, but I cannot get more than 1 pad recognized in the game.

Win 7 64 bit
Dlophin 2.0 64

You need to use the menu: Tools -> Connect Wiimote 1/2/3/4, or the keyboard shortcut alt+F5/6/7/8.
