Never mind – I figured it out. I checked under “My Account” on this site, to find out why I couldn’t reactivate the license. Under “Manage sites” I saw that the site URL associated with the license was actually the development site URL (a subdomain) – it wasn’t updated after the site went live several months ago. I disconnected that site then added the correct one. Then I was able to update the plugin and after that, activate the license (in that order – wouldn’t let me activate the license before updating, strangely).
Ron Divr – maybe a similar issue in your case?
It would have been helpful if there had been some kind of message on the Licence admin tab indicating that the license was associated with a different site URL and to login to my account to update it.
Thanks,
Teresa
