Wii remote wont work after installing wii fit

From Nintendo:

1. Turn the Wii console power OFF by pressing the POWER Button on the front of the console. Unplug the power cord from the wall outlet for a few seconds. After a few seconds have elapsed, plug the cord back into the wall outlet.


2. Turnthe power of the Wii console ON. When you see the Health and Safetyscreen, open the small flap on the front of the Wii console to find ared button labeled "SYNC." Press and hold the SYNC Button down for 15seconds. This will clear all the syncs on the Wii, allowing you to geta clean start to begin the process described below.


3. After holding the SYNC Button on the Wii console down for at least 15 seconds, you can now "re-sync" your Wii Remotes:
   
   
   1. Withthe first Wii Remote you wish to sync, remove the battery cover on theback of the Wii Remote to find a small red button just below thebatteries.
   
   
   2. Press and release the small red button just below the batteries on the Wii Remote; the blue lights on the front of the Wii Remote will blink.
   
   
   3. Quickly press and release the red SYNC button on the inside of the white flap on the front of the Wii console (picture).
   
   
   4. When the Player LED blinking stops and stays lit, the syncing is complete. The LED that is illuminated indicates the player number (1 through 4).
   5. This sync procedure (steps "a" through "d" above) must be followed for each additional Wii Remote added to the system.

Resync your remote and your wii then sync your wii fit board and your wii. I had the same problem on Xmas day!
