key already in use.
hello everyone.

Today, I had to change my hard drive, so I have reinstalled my games in the new but i'am unable to connect to game for windows live.

whether in super street fighter 4 or street fighter x tekken, it always told me the same thing "the product key you provided has already been registered to another profile."
error code 80151801

I don't see whence this problem because I'm 100% sure that the account that I want to connect matches the key entered.

if anyone knows how to fix this, it would help me a lot thanks

M$ changed how it handles passwords and serial keys, just change the passwords for the affected accounts.
