Doesnt work

I use to love this app, even bought the full version which I believe I paid $16 for at the time (now 20.99). Hasnt worked for months now, havent use it once in 2016 cause it just closes as soon as you open it. VERY disappointing and frustrating. Please fix this, I am not happy I paid $16 for nothing. I have no way to even contact the company to complain as they deleted their app support link.
