It seems that Clickbank didn't function on April 4th. The news stated that "On 2007-04-04 from 7:26 a.m. PT until 7:35 a.m. PT, ClickBank experienced a brief but unexpected system outage. During this approximately 10 minute period, the website was unavailable and orders were not processed. Hoplinks were unaffected during this time. We are working diligently to prevent this from happening in the future." So we lost some of our sales in this breif time.
it's only 9 minutes... just hope that you werent so unlucky as to have missed a sale during those 9 minutes
