If you are using MSN Explorer, you will need to contact MSN Support. This forum is for discussion of Windows Live OneCare. It is hosted by Microsoft, but it is a peer to peer discussion, meaning users helping other users. The moderators are volunteers.
Furthermore, if you are an MSN subscriber, you have access to free support. If you are using an older version of MSN Explorer, I'd recommend switching to Internet Explorer as the older versions of MSN Explorer are no longer supported.
