Won’t open

I have the most powerful MacBook Pro you can buy today and it still doesn’t work for me, it simply won’t open, I really enjoy this app but I must give it a 1 star until this problem is resolved, I will give it a 5 star after it has been fixed.

2013 Fall MacBook Pro with Retina Display 15.4"
2.6 GHz Intel Core i7
16 GB Ram
1TB Memory
NVIDIA GeForce GTX750 2GB VRam

P.S. I’ve had this problem ever since OSX Mavericks on my old MacBook Pro 17"
