I can't get the trial watermark to go away after upgrading to pro

I’ve tried deleting project settings and this failed.

Restarted unity, restarted the machine.

Is there another config file or something I can change to make the “trial” watermark not appear?

Can you help?

I’m not sure what to do next.
