When you say Netflix won't even load, do you mean the app/website no longer works, or that when you try to watch something the title tries to load, but never does?
If it's not either of these things, can you further describe what it is that's happening with Netflix?
Also, how do you view Netflix? A computer going to the website? The Netflix app on a computer? A Roku device? Netflix app on your TV? Another device? Etc.
