Is Widgetbucks screwing us with CPM ? Tested with 200000 Impressions !

Hi,
I am not a big fan of widgetbucks. But i decided to test them before passing any judgement on them. I ran their CPM on my site for a week to test it. I had good results for the first few days, but for 27th and 28th of this month i gave them a total of 200000 CPM Impressions (thats a lot ) and the CPM revenue is 0.00 $ How is that possible ? I can see the ads on my page, i can see them from other computers and even through proxies. So where is my money ??
