As I've wrote you by email already, several times, if you don't have *any* serial number, you need to retrieve one.
To retrieve one, you need the email address that was used when purchasing. You told me by email that your friend that bought you the scenery now moved to Russia and has changed email, so I replied to you that you can either *ask* him (using his new email, I hope he's reachable in some way) what email address he used to purchase the scenery (it doesn't matter if it works or not now), OR that WE can check your order status and serial number, by simply searching by NAME and/or SURNAME, so I wrote to you that, if you would give us his name, we can found your order, and to that question, you never replied. I'm sure you still remember his name, even if he moved to Russia...
