Help with license

Hi guys, I got a RB Metal I had to re-install Routeros using netinstall (brand new board stoped working).
At boot I got message “Router has no software key”.
In my account I set Routerboard as hardware and I put Software ID displayed on RB: N2RT-SXWV
I get my license -----BEGIN MIKROTIK SOFTWARE KEY------------ xyz -----END MIKROTIK SOFTWARE KEY--------------, I select text and copy as displayed on Wiki, then System → License → Paste key.

Tthen I rebooted radio as requested in nwe window.
At boot again License window showing different Software ID…
How can I get board wrking again? What’s wrong with procedure?
Due new software ID, have I to create new license key???
Thanks.
