Movements of Wiimote not registering?

[Ninjuto]

So, this problem is rather weird. I'm playing Okami and just got to the first part where you have to move our wiimote to draw a star but when I wave it around, the brush isn't moving. The game didn't freeze or anything, it just won't move. I find it odd as when I shake the wiimote to do the dash, it registers and everything else seems to work fine.
