Recently my Windows Live ID has been blocked. I didn't find this a problem, though. I just made a new windows live ID and managed my emails and stuff on that. I could still use my xbox account, because it was saved onto my xbox 360.
Yesterday, however, my account corrupted, and I can't use it anymore. I tried downloading the profile again, but that didn't work due to the credentials not being right, a.k.a my windows live ID is blocked. I've tried getting it back a few times, but that didn't work.
I still have a USB made for xbox that I used to transfer data from my old xbox 360 arcade to my new xbox 360 Slim. On my friends xbox 360, the profile is still there, unharmed. Can I copy the account to the USB stick, then put the account on my Xbox 360, and continue playing?
