Cannot Get the App to open – LensLight Visual Effects Review

I see all the great reviews on here but I’m not happy. I paid for the app and downloaded it but every single time I try to open it, it force closes on me and I can’t do anything with it. I don’t see where an update is available. If someone could help me out, I would appreciate it.
