it can take a while. IIRC the karma job (whenever it may be running..... once a day, once a week, every hour... i have no idea) only takes a few profiles each times and re-calculates their karma. so it could well be other people's karma has been updaten meanwhile but yours hasn't.

(of course this doesn't rule out the possibility that there's still something wrong with your profile or with the karma calculations. i'd just recommend to wait one week before taking further action)
