Just updated iPhone but app store & kik don't work?

I just updated my Iphones software to 6.1.6 today, and after a bit, Kik stopped working and wouldn't load my conversations or settings so I deleted it. I tried to go to the app store to reinstall it, but its not loading. What should I do?

Added (1). Yeah, i'm connected to the internet. Should I restore my phone?

Check to see if you are connected to the internet
