You could try this link and see if it gives you the "Claim Your License" option: https://www.eventideaudio.com/store/free-h9-plugin-series-bundle.
If not, then your Max was probably never registered properly. You should email email@example.com with your Eventide account name andH9 serial number, and we can get you sorted out there.
Thanks for the reply. I opened a ticket. Definitely no claim my license tab available.
