Hi – I have the big ugly ‘out of date error’ but can’t get the upgrade option – I get “There is an update available for The Events Calendar: Community Events but your license key is out of installs. Visit the Modern Tribe website to manage your installs, upgrade your license, or purchase a new one.” – but as I only bought this in May 2013 I am not out of installs. What do I do to upgrade? My calendar is down right now!
