When I try to change my username the star ask me this

"Security Check; Password:"

I put my pass and then I have a box that say:

"Your password did not match!"

What is happening? I'm sure that this is my pass

You have to change your PW, sign out, then back in again. Then try.:) It should work, I had the same problem.xP

Thanks :D now it works

c: Congratz on the name change!
