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?
