I tried to reconfirm and the form wants the date and the number of the first ad displays and some other account stuff.
Im pretty sure that the information is correct as I copy/paste everything, but I just get a mail saying that the answer to the security questions were wrong.
One thing that spooks me is that there are two boxes for Name. I guess one of them is the AdSense account name and the other is the Google account name...
Any suggestions or hints are welcome :-)
