Okay,I and a lot of other people have been having the Storage Device Lost glitch.
However,for me the glitch is not happening in 400 Days. It happens in Episode 2,right when Lee tackles Andy.
I HAVE downloaded 400 Days,and I'm playing on an Xbox 360,and I'm playing on a disc.
I have checked,and it is only happening with this game,so if anyone could give me any kind of advice on how to solve it,I would appreciate it.
Hell,I made an account just for this post,because I was so pissed about this glitch.
