Error message for Fsx Zurich upgrade

[miguel]

I have new computer using vista. Using Fsx only.
Got to page where option for reinstall is shown. I do this.
I insert original order number to get full copy of this scenery.
Get message:then simply use the "Register Serial" feature to activate your Serial Number (found in your email receipt) on the new machine. When I do this I get message I have to use orignal download that I purchase which was Fso9. Can yu say to me what to do? Miguel

eSellerate server reports error:
The order information you entered does not match our records. Please double-check your entry and try again. You must be using the same version of the software to reinstall as you originally used to purchase.

(error = 5481:9378) This is whole message I receive. Miguel

You need to use the "Register Serial" function to reinstall, the one that asks for you Serial Number only, NOT the server-assisted Reinstall ( "Reinstall" button ), that asks for the Order N. and email.
