I downloaded and reinstalled GSX...the readme says 1.9.9.4, the program version in the file properties says 1.9.9.5, and the "About" icon in the customize menu has no information at all about version number. Where do I find the unambiguous actual version number of the currently installed GSX?
The GSX "version" is not something that it's easy to define, since a lot of its files are *downloaded* when the installer is running so, even if you have an installer which is not totally up to date, you will STILL get the latest "version", provided nothing in your system is *blocking* downloads, like an antivirus or an anti-spyware program.
This means, if the download of updated files hasn't been blocked (but you should have seen warnings while installing), and if you installed recently (last Live Update was August 10th), you can be reasonably sure you have the latest version.
The issue is, BOTH the issues you have reported, the problem with some 3rd party sceneries using SODE and the automatic exclusion of AFCADs with no parkings, are SUPPOSED to be fixed in the latest version.
So, please, try to run the GSX installer again, now, and see if the problem is still there. If it's not fixed, we'll try to investigate using this scenery.
