Hello Guest,
No need to worry, I understand your predicament and will do my best to assist you in finding a solution for your lost product key. Your English is perfectly fine, so don't worry about that either.
First and foremost, I'd suggest you check the email account associated with your Microsoft account, as it's possible that you received the product key there when you initially purchased FSX Gold Edition. The email might be buried in your inbox, so be sure to search for keywords like "Flight Simulator X" or "product key."
If you've had no luck locating the key in your email, another option is to contact Microsoft Support. They may be able to help you recover your product key if you provide them with enough information to verify your purchase. You can reach their support page here: https://support.microsoft.com
However, I must mention that since Microsoft Flight Simulator X is an older software, they might not provide support for it anymore. In that case, you could also try reaching out to Dovetail Games, who took over the publishing of FSX: Steam Edition.
As a last resort, you might consider upgrading to a newer flight simulator like Microsoft Flight Simulator 2020. This would not only provide you with a new product key but also grant you access to a more advanced and visually stunning simulation experience. You can find more information about Microsoft Flight Simulator 2020 here: https://www.flightsimulator.com/

I hope one of these suggestions helps you resolve your issue. Good luck, and happy flying!
