I want to change my username to "dx4".

I've read the help page and when I visit http://community.wikia.com/wiki/User:Dx4 it says the user doesn't exist.

However, when I try to request a username via Special:Contact it says that someone already has this username.

What should I do to change my username to "dx4"?
