A few days ago, my XBOX 360 asked for my password when I signed into XBOX Live. Every time I enter it, I get the error code "80151011". I went to THIS PAGE (http://support.xbox.com/en-US/error-code-lookup) and followed every solution. I cleared the cache, updated my security info, deleted and re-downloaded my system update...and every time I still get the 80151011 error. I deleted my XBOX Live Profile and tried to re-download it. It says "welcome back Loftin08" or something similar to that, and it displays a status bar, which fills to about 5% or 10% (of bar being colored in, no numbers shown), and then I get the 80151011 error message again. I am able to sign into XBOX Live on my PC with no issues. PLEASE help me get back to my console.
