Razer Cortex "Failed to Start"

So for the past week, ALL of my Razer Central apps have refused to work. They don't start at all. I can't get into the UI or anything. (Cortex says "Razer Cortex failed to start, please try again.) I've been with support trying to fix it for 3 days and nothing. Deleted all files, registries, reinstalled, blah blah blah. The whole shtick. How do I fix this? Do I REALLY need to Reinstall windows for something so trivial?
