How do I correct a misspelling in my url?

I have
http://awordfiltyspokenmagazine.bravehost.com

I want
http://awordfitlyspokenmagazine.bravehost.com

transposed the letters in fitly ... and got filty instead
I do not want to have to delete the whole domain url
and set up another account.

PLEASE ADVISE .... I'm running out of steam
