AdBrite has been pretty bad since 2009 year. I would recommend switching to some other ad networks such as AdSense or BidVertiser.
change BLA , they are on the top down now you wasting traffic with them , I hope they come back like old days
I am using adbrite and making over a hundred a month and this month forget about it it just terrible. I noticed a big decline the first week and saying to my self WTF is going on. I am giving up on them and put adsense back on all the pages. I tried adsdaq and had adbrite as a backup in the second week of this month was doing good then they started can even keep up the fill the end of last week so it's back to adsense.
