Works great for this and lets you delete any user lines you don't want in the database.
Just use the "Browse Data" tab to select "user", then the "Execute SQL" tab to enter:
INSERT INTO user VALUES ("0", "0", "0", "0", "0", "0","false") for the AuraHD (You can cut and paste this) Click on the "Execute query" button.
Go back to the Browse Data tab and "user", to select and delete any records you don't need.
Luck;
