Not sure where to post this but i cannot login to my account on my 360. It'll stay on for about 2 seconds and then say i was logged in on another console. So then it proceeds to knock me off live on my end. So after this happened 5 or so times i noticed my gamerscore had changed. Checked that out and got 3 achievements from FIFA 12. I don't own Fifa, nor will play FIFA cause i'm not a soccer fan. I also have my xbox passworded so no games can be played unless i type in the code. I'm the only one that uses this account and noone knows my info but me. So how does this happen?
