So ... exactly how am I supposed to get the SR2?

 

I get to the updates page, click on the update, get asked for my serial number, enter my number, press continue and I get an error message saying: 

We’re sorry, we were unable to verify your serial number. Please try again, or refer to our Serial Number FAQ in the Support Area. results:0 Serial Number is marked - check status. Not exactly helpful: "check status". What's that suppose to mean?
