can not get Aim offset to line up with center of screen

Hi guys I’m playing around with the Game Animation Sample project, and i can’t seem to get the aim offset working correctly. the Aim Offset never lines up with the center of screen, it’s always off and i can’t work out why, i have tried a few methods, i used the same setup as i have in other projects that worked fine but No good, i found a few projects around the Net that have Aim offset that uses a Modify bones and the AO X and Y but when i add a Dot in the screen space it suffers from the same problem, i used a blend space and all that Jazz, got controlled rotation and so on, but it all suffers from the same issue some worst then others. any Tips on what is going on,
