Yes, like jroberts mentioned, it's better to contact their official support. However I doubt you will get any result. Regardless of that, best of luck on refund!
I tried refunding it as well, but it didn't work. Then I tried disputing it over Paypal, but for some reason I wasn't granted a refund. So now I'm out a game and $60. I will be having a second though about buying X-Plane in the future.
