Important Note!
Do Not use "One-Time Mode" sync.
Syncing can be completed only if a compatible game disc is running in the console.The Wii Balance Board may need to be synced to each compatible game individually.Some games may require you to go into a specific screen to sync the Wii Balance Board.These sync settings will be saved even after the console is turned off.

If you haven't already tried to replace the batteries, do this (if you have, this is useful information to include in your problem description :D). If that hasn't worked, you may need to re-sync the board with your Wii.
1. Power on your Wii console (there is no need to power on your balance board at this time).

If this does not fix your balance board, it may need to be repaired or replaced. Contact Nintendo and provide warranty information if applicable.
Good luck!

Synching can be completed only if a compatible game disc is running in the console. Compatible game discs (such as Wii Fit) will display the Wii Balance Board icon on their packaging.
The Wii Balance Board must be synced to each compatible game individually.
These sync settings will be saved even after the console is turned off.

Follow these directions to sync the Wii Balance Board (so that it is recognized by the Wii console):

Insert a Wii Balance Board compatible game disc (such as Wii Fit) in the Wii console.


Use the Wii Remote to select the Disc Channel from the Wii Menu, then select "Start" to begin the game.

Open the SD Card slot cover on the front of the Wii console.

Remove the Battery Cover on the bottom of the Wii Balance Board.

Press and release the SYNC button on the Wii Balance Board. The Power LED on the board will start blinking.

Press and release the SYNC button on the console while the Power LED on the board is still blinking.

The Power LED will stop blinking and light steadily once the synchronization is complete.

Put the Wii Fit game disc in the Wii and start the game. Then open the small SD Card slot cover on the front of the Wii console then remove the battery cover on the bottom of the Wii Balance Board. Press and release the SYNC button on the Wii Balance Board. The light on the board should start blinking. Afterwards press and release the red SYNC button on the Wii console while the light on the board is still blinking. The light on the balance board will stop blinking and stay on steady once the syncronization is successful.

Put four AA batteries into the battery housing located on the underside of the Wii Balance Board.

Insert a Wii Balance Board compatible game into the Wii system.

Select the "Disc Channel" on the screen with the Wii remote, and choose "Start."

Open the SD card slot to reveal a sync button on the Wii system. This is located behind a cover under the power and eject buttons.

Turn the Wii Balance Board upside down.

Remove the battery cover under the balance board to reveal another sync button.

Pres the sync button on the balance board, then press the sync button on the Wii. Do not hold down the buttons. You know it is synchronized when the blue light on the Wii Balance Board stays steady

Place the board on a flat surface directly in front of the TV. Face the power button away from the TV.

I'm afraid the only way to play Wii fit is to use a balance board. That's why it wont let you past.

First you need to press the red sync button on the balance board, then press it on the wii. After the first sync it should start automatically. If it starts having problems with lag or anything else, try taking out the batteries of the wii fit balance board and then resync it.

Hope it helped.

I know it's been a while since you have posted and have prob already figured it out. But just in case this may help someone else. Try turning off your wii and unplugging from the power source for a few minutes. The plug back in and turn on. At the initial warning screen press and hold the sync button on the wii console for about 4 sec. You will have to resync your wii remotes. Next make sure the disc for the game you are going to use the balance board with is in the system and start the game. Then try to sync the balance board.
