How to edit the scores?

Hi,
i want to edit the scores to erase some names that were written wrong whithout having to erase all the scores but i cant find the score file. In UltraStar the file was really easy to find but i have the Deluxe version now, and i cant find it, dont matter how hard i look.
Can someone help me?
Thank you

oups
it's true, the first version of ultrastar it's easy to change score !
but with the news versions... i think it's more difficult
i don't know sorry
