I just splashed a chunk of this month's pension on X-Plane 10. It wouldn't install until I downloaded an installer. Then it wouldn't run because it said I'd moved some files ("No,No.No") which I hadn't. Then it insisted it needs a serial number to register. The number printed on DVD11 doesn't work, and the barcode on the box doesn't. So where do I get mny serial number? There's nothing in the instructions.
