URGENT: Problem with date configuration

I just purchased the annual subscription to Popuo Box.
The trial version showed the option to schedule dates for the popup to appear.
I downloaded and installed version 7.9.3 and I couldn’t use the function I need, which was the reason for the subscription. The function doesn’t appear.
Please advise me, because the popup needs to be displayed on non-consecutive days and this feature appeared in the trial version, but blocked. I clicked to unblock it, paid, and nothing happened.

Help me.

Urgent.
