Yo guys. I´ve got a wii since quite a long time. I had one wii remote control which was registered on the wii console automatically. I´ve got my second which I´ve registered manually. Yesterday, I bought a wii balance board. I tried to connect it today, and my little sister helped me. too bad she pressed that synchro button on the board for more than 10 seconds, which deletes all registries of all remote controls. now I have a problem. I have to unregistered remote controls and a registered balance board. I can´t enter wii, nor can I do any settings. simply becuz the remote control doesn´t react. How can I register it again? I can´t click the "home" button. nothing reacts. I don´t know what do do anymore.

help is appreciated. thank you in advance.

Not completely sure, but i think you need to turn on your Wii, then press the red synch button on your Wii (the one behind the SD-card cover).
And then press the red synch button behind the battery cover on your Wiimote.

Repeat for each device.

I think it's the same for the balance board, you press the red button on the Wii and then the button on the balance board.

If this is not correct just check the manual that came with the wii, it should explain it properly.

thank you sir I found something promising in the web and it worked. I had to delete all devices first, trough holding the synch button for 15 seconds, and the register each device new again. everything works now, took me quite a while but it works. thank you.
