Can't even use it – Intro + 3D Movie Trailer Maker Review

Hi, my biggest concern about this app is that I can't use it. I was really looking for a perfect app to make intros for my YT channel. When I first opened the app, it asked me if I wanted to subscribe and have a 3 day trial free. I couldn't even get into the app. Please fix it and thank you for your time.
