Registration Problem: Username had already been taken?

My forum has 2 members, I'm trying to make a tester account to test some things and when registering it, it says "Username is already taken" no matter what name I put in. 

Help? My forum is [url=nascarboards.forumotion.com]n[/url]ascarboards.forumotion.com, I tried on different browsers, nothing worked.

Could you make me a test account and I give you the results ?
 Welcome to the forums by the way! 

Hi,

Go to Admin Control Panel --> General --> Security --> Unauthorize subscriptions made with the most commonly used spam usernames --> No --> Save

You should then be able to create an account with that username.
