stuck in demo mode

I downloaded this program a few months ago and didn’t activate it. Now it doesn’t accept activation key. Tried unistalling it and reinstalling - no luck. Licence dialogue box says upgrades allowed untl 11.4.14, which I guess is the problem. Any ideas?

Hi Fiona, have we spoke on the live chat on our website? If so, can you please send me an email with a reference link to this forum topic to mcgregor@emclient.com?

Thank you,
Paul.
