Conditions that May Produce the Error:

The lock-up error may occur in instances when all of the following conditions are met:

Two or more sets of user data were created in Wii Fit or Wii Fit Plus and the data created earlier was deleted.
A Mii character used in Wii Fit or Wii Fit Plus is registered in the Wii U Mii Maker.
The data from Wii Fit or Wii Fit Plus is transferred to the Wii U.


How to Resolve the Error:

If you encounter this error, you will need to delete any Mii characters in the Wii U Mii Maker that were used in Wii Fit or Wii Fit Plus, start Wii Fit U, and then transfer user data.

If the Mii character that needs to be deleted is the user’s Mii character, please follow the steps below to change the user’s Mii character:

From the user selection screen, highlight the user.
Go to User Settings.
Select View/Modify User Information.
Tap Next to enter the user’s password.
Select Change Mii and choose a new Mii character from Mii Maker.
Delete the user’s original Mii from Mii Maker.
Furthermore, if the deleted Mii was being used in other software, the user will have to re-register their new Mii character with each piece of software.

To use the deleted Mii character with Wii Fit U, after transferring all user data, the user must once again go to the Mii Maker and then select Copy from Wii Menu.
