So i have had forza 5 for a while now, it worked perfectly until a couple days ago when i found that it uninstalled itself. So i reinstalled it and now it refuses to work. Itll load then after it goes to the screen where it says the copyright stuff, it boots me back to the home screen. I have tried power cycling and all that other stuff, but to no avail it still refuses to work. If anyone has an answer that "WORKS", let me know.
