Account creating

Hello, I need help with this (and probably not only me). I tried to create a new account for some time, but whenever i try to click "Create Account" it shows me this :



"There was an error creating your account. Please re-enter your account information."



Some friends also have this problem, so I think it is not my fault :/



Is there any solution to this ? Anyone have a problem with it too ? Please answer and thanks :)
