When I attempt to install it I get a "RAGE cannot be installed yet, because it has not been released". I have the physical copy in my hands, there is no clause in the license agreement that says that it can't be played or run by/before/at any particular date, therefore I want the product to work. There is a very resonable expectation that if I have a physical copy of a product I can use it and it will work. Therefore I'm reporting this as a bug.
You're lucky! You're obviously in Australia too. I got my copy, put in what I thought was the key and was greeted with "Invalid Product Code - The product code you have entered is not valid"
Did your key start with STI-RAGE-EAU-xxxxx-xxxxx-xxxxx? Mine looks like this but to me doesn't seem right for a key, more a packaging code, etc
