You probably don’t want to be showing off your key,

Have you linked your iLok account to your Eventide account. Go to your Eventide profile and right down the bottom there is an option to show your plugins.  If you aren’t linked, you’ll be prompted to link. If you get to a plugin list and your Ultrachannel isn’t there, try to register it again.
