I recently had a problem with my Live account. I was sloppy enough to right wrongly my own e-mail (I wrote "hotmal" instead of "hotmail") and now I can't access Windows Live Messenger and buy the Xbox Live Gold account.
I was already informed that you can't help me to change the e-mail (you told me that I'd have to go directly to Windows Live ID support, but they haven't helped me either), so I was wondering if I could create another profile (with the right e-mail adress) and transfer my progress to this new account. Would that be possible?
There are a few games that will allow you to transfer save files to other profiles although I believe you will be unable to earn any achievements from those. Otherwise, nothing can be transferred between profiles.
