Microsoft Screwed Everything

Been using it for the longest time, suddenly update one day, hop on and Im signed out, type in my email and the Microsoft image pops up and my account that Ive had for 2 years no longer works. Why would they ever screw so many of their users over like that. Do they want me to convert to a microsoft account? Make my email one? What? I dont get it and until its fixed or explained you get 1 star, plain and simple.
