Once after downloading and using the Internet Browser (to post here in a topic that was for internet browser users), I went back to play Zelda, but only the A, B, Plus and Minus buttons were working. I could only move Link and use the items I had equipped last time I saved.
I didn't have to call Nintendo's Tech Support, though, because my sister somehow knew what to do.. I don't know what she did, but she did it to both Wiimotes anyway, just to be sure.
The only problem (or minor annoyance) I have now is that my system gets really warm after extended periods of play.
