The first two disks install FSX the third is supposed to install the Expansion Pack [which it has not]; I have no F-18 in my aircraft inventory. :-[ Ay, mate! Hi Steven, Where did you buy it? In other words, are you sure your new FSX Gold Edition is an original (authentic) one? I ask because there is a lot of fake FSX Gold Edition to sell online. I only trust in the products sold by Microsoft store, e.g. http://www.microsoftstore.com/store/msusa/en_US/pdp/Flight-Simulator-X-Gold-Edition-PC-Game/productID.253657900

You should be able top trust the more respected sales stores (Amazon, PC Aviator, FSPilotShop, TheFlightSimStore, etc.) for purchasing an original copy. Buying from eBay, or the likes, you run the risk of getting non-genuine article.

When buying from eBay, I look for good reputations (99.5%+) from sellers of a large quantity (1000+) of goods. I only ever got one thing that wasn't what I thought it was. That was totally my fault. ;)
