So last night, I was playin' a game, and it froze. After pulling the plug on my Xbox and rebooting it, everything is a lot slower. Not only that, but it says I have no profiles on the console (there'll be a picture of what the screen says at the bottom). I know the accounts weren't deleted, because I can still use my primary account on Xbox.com. I've already posted this on the Microsoft help forums, but god knows how long they'll take to respond and if they'll even be any help. So, if anyone has any idea what happened and how to fix it, it would be much appreciated.
EDIT: It supposedly erased my entire hard drive but at the same time, the console also says I have the same amount of free space on it as before the incident. I'll probably have to send it in to Microsoft, but if I permanently lose all my stuff, I'm gonna be pretty pissed.
