I have been using my Xbox without issue since I bought it. I have a Xbox 360 Slim with the internal 250GB S Hard Drive.
Tonight it randomly no longer recognises my profile on my Xbox. It takes a longer than average time to load up the dashboard and then asks me to create a new profile.
I have a lot of stuff saved on my hard drive, ranging from saved games, apps and DLC. Any reason why this has happened and any fix to get my stuff back.
