Sometimes this could happen if the site is on the restricted list. Go to IE,
Tools, Internet Options, Security, Restricted Sites, Sites, and scroll
through the list and see if the site that you are trying to access is listed
or when you try to load the web page, Look down at the Bottom Right Hand
Corner of your IE Browser and see if it says Restricted, if it does than
perform steps mentioned above. Another Option is to reset your IE Web
Settings and then redo your Active X List as you already have, repeat what
you did to change the ActiveX Part.
Hope it helps you and Good Luck,
