ABR - problems?

[Spliffmonkey]

Hi guys - anyone know why I might be experiencing problems with my PR rankings? Been a master Gunnery Sergeant for ages now and a friend (who I introduced to BF2 and then PR) overtook me last night, despite our scores and time spent playing being relatively equal

Could it be my profile is corrupt - or am I just cr*p?

Any help / advice is much appreciated

Thanks
Matthew
