I can't register my parallels 11 on the new mac air

[PatrickC17]

I've already sign out and remove the parallels 11 from my old mac air. But I can't register my parallels 11 on the new mac air. the system remind me "Unable to confirm the product license".
Could you help me reset the activation Key?
