Hello,

If you don't have any data yet, then please open the menu by clicking the icon in title bar then press `ALT` +`SHIFT` key and there will be a new menu to reset data. Keep pressing the buttons and click reset data. This will reset the database and you should be able to start over.

If you already have data, then please don't reset data but go to reset password and press `ALT` +`SHIFT` there will be new link at bottom to reset the default account `_admin` You can click to reset the password and login using the new password.

Thank you
