Well I have even went as far as messaging the guy on XBL, but i still can't get it to work. he said:
It should auto sign in the second unused profile. You need to be ready to hit X and sign in the second real profile as soon as you see the first one pops up as signed in. Sorry but I do not have a web cam and can not make a video.
I asked if he had a video of how this worked for him, but that was the response.
I STILL cannot get these stats to erase or anything
. any ideas? anyone have luck. I wouldn't mind getting rid of this game forever, but as long as this one achievement is still here, the game stays.
