Lost my key to login to live.com.

I bought the Dark Souls: Prepare To Die Edition. Several day ago I lost my key to the game. I looked for it everywhere, but I do not find it. To save the state of the game I must log in and enter the key. I have been looked for some help in Games For Windows.
While I switch on the game and I had to entered the key, the text displayed: I need a key. I pressed it, but I did not receive help.

Can somebody help me? What should I do?

Migrate to a new XBOX live account

Can anyone help?

I have 2 accounts, the first with a gmail.com login (old one been using for years). The second is a live.com login.

I want to migrate all my settings and achievements from the gmail.com account to the live.com account (gmail.com > live.com) then close off the gmail.com account without losing content.

I can't seem to find a way to do this. Can anyone suggest how this can be done?

Where are you trying to reset your live id password? If you want to reset it you should login to login,live.com and reset it there.
