Doesnt open anymore after update

I use to love this app for hunting and fishing- and although it isnt 100% guaranteed that it shows when I will get the most action in that day, it has been right multiple times. Gravitational pulls of the moon even effect people, the tides, sleeping and awake moments. If anything it helped break up a long day of hunting where I could tell myself to be extra alert. The new update that is on the same system for iOS 7 wont even let me open the app. I cant believe that I paid money to a company that wont update their app to work anymore and just wants me to spend more money on a different version? I want an update or my money back please!!
