BlackGold Wont Open

I used BlackGold for a year and it worked well. Now it only opens to the Splash Screen then closes. I have restarted my iPhone but no luck. I uninstalled and reinstalled, but BlackGold will only open to the Splash Screen then close. It will no longer work on an iPhone version 7.1.2 .
