I was undeer the impression, the poster was asking if you cleared your cookies, it could have been the problem with your not being recognized by the SS site, which would have been correct.

Just click it everytime you log on, and keep in mind, if you ever shut down Internet Explorer, it may clear your cookies and that would be the problem.
