Ah, see. You typo'd it into the registry
The last 8 of your VIN (as you just posted) is: 9H520338
The last 8 of your VIN that you CURRENTLY have on the registry is: 9H520388
See the difference?
you have one too many 3's and one too little 8's. Correct that typo within the registry and you should be set. Though, your car isn't in D1 yet so vinwin won't show you anything yet =(
