Login with pin does not work, why?

Got a laptop today and just wanted to log in again but then this message always comes, what do I have to do?

Pick up a hammer and bring it to an end.

Pon personalized? So even a pin chosen?

Yes

Then give this pin too

I can't

Is actually in the message in it. The pin is no longer valid because of any change. So register with password and re-assign pin.

But only goes bad, because only on the screen, the message comes.
