App suddenly stopped working

Just purchased this 2 days ago and now it will no longer open! Am very frustrated. Followed through on the instructions and when it worked the 1st time was reall happy with it. BUt now it won’t work anymore and now I can’t control my webcam like I could and needed to do so before. Help! I wonder what the heck happened????? ;’(
