NETFLIX WON'T LOAD ON MY SMART TV (LG)

Netflix isn't loading on my brand new smart tv that I have recently purchased not even a week ago. The app was working perfectly and now it just loads up for a second and goes to the black screen until I hit the home button. This is realllllly inconvenient seeing as the app was working FLAWLESSLY not even a few hours ago. VENT OVER!
