This problem occurred today and its quite confusing. So usually when I turn on my console my profile is signed in automatically and no problems occur as I have chosen the option to sign in at system power. Today I turn on my console and it takes a while longer to load up, and instead of loading my home screen it loads the sign n menu where it shows all of the avatars next to the given profile. I thought nothing of it as its happened before but when I checked for my profile it was not on the list. So I checked a few times to make sure and it was not there. I then signed in to my friends profile and checked his friends list and looked if I was still there and I was, So I knew my account still existed. After that I hooked up a second controller and went to the sign in menu to try and sign in and my profile wasn't there either. Then I went to the system memory and checked my hard drive for the profile and it was with the rest but instead of having the Gamertag it said "Corrupt Profile". I tried downloading and recovering it as I would if I were at a friends house but it would stop a bit into the download and give me a pop up saying Profiles cant be downloded at the time. I dont know what to do. If anyone can help I would greatly appreciate it.
