Hi guys, I don't realy know if this is the right place to ask but a few years ago i bought dirt 2 , and now i wanted to play it again, but i have a new pc and i absolutly can't remember my windows live account. Mainly because i never use it since GFWL suck's . Is there any way to retrieve your GFWL account when you still have your cd key but can't remember any of you login information? I just wanna play single player but i'd like to save my progress..  Greetings W
