For the past month or so, I've been unable to do ANYTHING on my 360. It's alternating between error codes 80072ee2 and 800705b4. I've been on more forums than I can count looking for a solution, and found none that work. I have reset my connection settings, reset my router, deleted my cache, reformatted the HD, deleted and redownloaded my profile, and did a system reset. So far, none of it has worked. At first, I couldn't even sign in to Live. Now, I'm signed in to Live, but nothing will load up. Does anyone have any idea what to do to fix this problem? I would really like to be able to use my system, especially considering me and a bunch of my friends are getting Grand Theft Auto when it comes out tonight.
