Can't access my secure site

[ckmanser]

I recently started a website, but immediately got "this page cannot be displayed" message while trying to access my control panel. The host advised me to remove ZoneAlarm which I did but with no luck. I can access my control panel from other computers but not mine. I have run spybot and reviewed my IE 6 many times. My host said it may be a registry problem as I have Netscape on my computer and it can't access the site either.
Any thoughts?

I have attached the Hijackthis log which may help with my problem of accessing a secure site.
