I just graduated from college and moved out of my college apartment. My roommate signed up for Netflix and used my xbox to watch movies. Problem is, I decided to start my own account and I cannot get rid of his account off of my xbox. I deleted the app from my 360 and figured if I re-downloaded it I could enter a new account information. (It did not work.) So, how do I unlink his Netflix account from my xbox account and use my own Netflix account?
