Username issue

My other admin on my site http://www.computalks.com/
He tried to get the username Chris
It says the username is taken when it isn't.
No the username isn't blocked it's some issue that I can't fix for some reason.

Do a members search for Chris, also make sure you dont have the word censored, oh and make sure you dont have any banned members with the name,

Other then that? not sure? you can try and see if you can register with it?

I figured it out this can be solved.

ok cool
