Adbrite Adds, Not Showing? Just Me?

Hey everybody, ive just recently started using adbrite, and my add codes have been on my sites for about 3 days now, initially i figured that the adds not showing up was because it would take some time to set up or what not, however my sites are rapidly starting to pick up in traffic and the adds are still not showing, it is incredibly frustrating.
I was wondering? is it normal for the adds not to be showing up after 3 days or is their something else going on here?
If not how long should it be before i start to see a solid add rotation? or if this is a problem how can i go about fixing it.

Thanks for the help
