Forum Display Name

[Marceosues]

I am certain I did not give myself the display name "Marceosues", and when I try to edit it, it claims I'm not allowed to edit my own profile. Is there now way to fix this because I did not pick this name (I know it's just a forum name but it bothers the hell out of me that I wasnt the one to make this type of spelling error I guess) Also no one else has access to my account.
