Time machine setup

I am using My Book World Edition connected to an Airport Extreme.  My book world firmware is upto date.  I keep receiving the “Status Error - 6602” whenever I try to set up the “time machine” on my book.

I really need some help, it’s getting annoying.

thanks,

You might want to contact Apple to find out what that error means, then someone might be able to help you.
