While recording error and slow

[BlaBlaBla121]

I  use 1x, member, while waiting until 1 min and then makes the system gives the following error:

(cengizirem34) This nickname is used by another member

but he used to nick olmadığınada I'm sure. I would look at other pages while waiting for the last member of the nick, but still fail to try. and I did not reset register.temp register.php. napabilirim else?
