So i needed to go to bitcoinadress.org and there copy adress and key then use pywallet to create wallet.dat file and insert it to bitcoin core wallet.
Did you
import the private key into Bitcoin Core (bitcoin-qt)?
I'm not sure if pywallet can do this, it could be. But it sounds like you've used bit
coinadress.org to create a private key. Maybe you're holding a brainwallet.
