Not working

I loved this app but now it shuts down after 3 seconds and I have only had it for a month, I deleted it hoping I could re download it but now I have to pay for it, so Im guessing it was a scam to get u to like it then screw u over, I took videos and pics of my son and now I have lost them because the app dose not work
