same thing recently happening to me too 
i havent signed anyone now for a week, even though lots of clicks, should have signed up at least 10 with a several real money depositers(but stats show zero – which is impossible).
last month I tested and downloaded myself and it didnt show as a registration, i emailed my AM and after about 2 weeks they said that was linked to me…..hmmmm so why has it not registered a new registration ???
Now this month my stats are awfull at AP and this month might be my highest real money depositers so far overall) – so it make no sense for my AP new players to be way way down.
Anyway i referred somone i know to AP through my links – they have played well over 500 hands…..no registration showed up and no account in my player stats !!!!!!!!!!!!!!!!!!!!
Just waiting for Shenaz to reply to my PM
