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

KingoRoot on my Motorola droid 4.4.4 won't finish

So I tried using KingoRoot to root my Motorola Droid Ultra running 4.4.4 and I followed all the steps and it says "Root Succeeded" but the "Finish" button doesn't come up and it never reboots my phone or installs SuperUser. When it says Root Succeeded it goes to the end pag but it only says Root Succeeded and says "share on Facebook or Twitter" or "donate via PayPal" there is no Finish button to push so my root never actually finishes. Can someone tell me why? And is using iRoot recommended?
