Hello Padraic,
It appears that the trial version you had was newer than the full version you got. We have to update the trial version periodically to update the expiration date, but as there hadn't been any other major changes during that time, the full version hadn't been updated.
I've asked some other members of our team to furnish you with a newer copy and that should fix your issue. You should hopefully be hearing from them shortly.
Thank you,
Jimmy
