I've just installed Adobe Illustrator and I wanted to use the 7 days free trial option. But when I open the app; an add appears asking me if I want to purchase Illustrator, or if I want the 7-day free trial. So, when I click the last option, the add disappears for 3 seconds, and then it comes back. And I cannot start using the program because the add doesn't disappear and everything else is blocked.
