I was suggesting the yahoo site explorer as an alternative so that the process can be completed. The exact place to go to on yahoo is the link that I provided in my post. Since you say that you are experiencing this error all the time and it is not intermittent I have opened a ticket for you. If you can demonstrate the issue and reproduce it with regularity it will be much easier to look into this with you. To update your ticket or check on it's status login and visit your support history.
