I purchased KFLL (FS9) a while back. I am now trying to download and install the FSX version. I was informed the product was sold as 2 Products in One. This means, by buying one version, I would automatically get the other for free, since activation and serial codes are shared between FSX and FS9. However, I keep getting a weird message (see attachment) every time I attempt to input the serial number to activate the software. Any assistance would be appreciated.
