Users are reporting this with some amount of frequency. Furthermore the users are reporting being told to pay $40 or more to download the StoneCAD application!
Okay - first the good news. As of today Owens Corning's server has not been hacked or hijacked.
The bad news: the users reporting this problem have a malicious virus. This is a virus that is redirecting the request to the Cultured Stone site to a fraudulent site requesting payment for the StoneCAD software.
We (the StoneCAD support and development team - not Owens Corning) recommend if you encounter this error to go to http://free.avg.com . That's currently our favorite free virus scanning software. Download and install this tool and inoculate your machine. You could also dump your Windows machine for a Linux, or OSX machine - but that's another discussion all-together.
