Go to your Continuum Folder (C:/Program Files/Continuum by default) and right click on the file (zone.dat in this case) and click properties. See if read-only is checked in the General tab. If it is checked then un-check it. If that does not work and you are using Windows Vista open up the properties again, and go to the security tab. Hit "Edit..." and give full control to all the users and administrators. -CRe>
