PLEASE fix crashing problem

I downloaded this app a few days ago and used it to make two instagram videos full sized. It was simple, easy to use, and worked well. The only problem I had was that ads kept opening in Safari, which wasnt ideal but I could live with. Since then, I have tried to open this app approximately 20 times (no exaggeration) and it wont open/keeps crashing! This is so frustrating, seeing as it worked so well the other day. I see others have been having the problem as well so hopefully this can be fixed soon.
