I have been dealing with at least 2 critical account related issues on my XBox 360.
First, I kept encountering 80048821 whenever I turned on my XB (which told me either my profile's e-mail was not associated with a Live account or my password was incorrect -- both of which are false since I logged in just fine a hundred times before and I can log into this website). I tried many things to resolve this problem -- resetting my password on the account.live.com, adding proofs to my account, clearing cache, deleting and re-downloading my profile -- I did this many, many times to no avail.
I gave up for about a week and tried retrying all this, this weekend. I was still getting the same issue this morning, so I reset my password, cleared cache and deleted my profile... and now I'm getting an even worse problem!
What is that problem? I can't even download my profile now. When I attempt to do so, I enter my e-mail/pass info, Live starts to DL my profile, then stops about 10% of the way through and tells me the following:
Sorry, XBox Live profiles can't be downloaded right now. Try again later.
I haven't been able to connect to Live in 2+ weeks now. Can someone help me fix this problem? I hope when I fix this, I don't start getting 80048821 again.
