I am not from Laminar Research; just a flight simmer from downunder.
You are in the wrong forum. You need to take your problem to a steam forum. This forum is for those flight simmers using the genuine version of X-Plane from Laminar Research.
Steam is a 3rd party hybrid (modified) version of X-Plane created and developed by Laminar Research. Laminar does not sell the steam version. Steam is taking a commercial advantage of the original work by Laminar.
Steam is slow to update (days after) when Laminar makes an official release of an update whereas if you are running the official version you can make an update, including Beta versions immediately they become available.
Steam installs differently to the Laminar version. Steam does not and will not work with the Laminar version and vise-versa. There is not connection between Laminar and steam
I don't support steam.
