30 day trial only 7 days?

Hi,
Yesterday, I downloaded the trial version of Scrivener for Windows (Version: 1.8.5.0 - 27 Jan 2015). On the website and in all the documentation it says the free trial lasts 30 non-consecutive days. But when I start using the program the message that pops up says the trial version lasts only 7 non-consecutive days. Is this a mistake?
Thanks in advance for any clarification.

Have you perhaps run a trial of Scrivener in the past? Minor upgrades (i.e. a change from 1.0 to 1.x) won’t reset the trial clock, so any days spent in a previous version would count toward your total 30 days.

Ah! Yes, thanks Jennifer. I now have hazy memories of maybe running a trial years ago.
