A few weeks ago, my ads stopped showing, and I couldn't get them to show (as demonstrated by stats and backlinks in MSN.) This happened following my weight dropping to 0, and despite my weight coming back when I revalidated. I decoupled my two accounts, and started new ads and the 2nd account and they started running. About 6 days ago, my weight went to 0 and ads stopped showing. I revalidated and my weight came back. But it appears that my ads still aren't showing...My stats are still at 0 after several days. Am I doing something wrong? Or do I have to do something beyond revalidating to get my ads to show again if my weight mysteriously drops to 0?
