Tried KingoRoot and it said Root Succeeded but it didn't finish?

Sorry to post this again but I posted it in the wrong forum last time.

I tried to root my Motorola Droid Ultra running 4.4.4 using KingoRoot. I followed every step it told me to follow and it said "Root Succeeded" but the "Finish" button never popped up and it never rebooted my phone or installed SuperUser. The screen only said "share on fb or twitter" and "donate via PayPal". Can someone tell me why the " Finish" button never popped up or it never rebooted or installed SuperUser? I'm confused
