Hi simonigel,
I am not with Laminar Research; just a flight simmer.
This forum is for the official X-Plane software from Laminar Research. You need to take your problem(s) to a steam forum and not this one.
The steam version is a different product altogether. It has been developed by a 3rd party taking a commercial advantage of the development work by Laminar Research. You cannot mix X-plane by Laminar Research and the steam version. You will corrupt your files.
