I noticed there were problems with this glitch because of the NXE. I did a few "practice runs" of trying to see if its possible to sign in. Eventually I am able to do it, from either my internet just slowing down at the right second, or because I was fast enough. I am looking for a nice person to let me borrow their account with the Seriously achievement. If I get one, I will set up a digital camera and try to record it. Thanks!! Also, my gamertag is Patbini.
