Buildings on the other hand, are gone. This is what I show, and this is all straight P3D and FSDT. KLAS is at the top of my scenery, and I don't own anything ORBX.
It's not possible that changing the AFCAD to update the ILS frequency and a single runway texture for the markings would cause missing buildings.
Without any further details about how old was your existing installation was, and the rest of your configuration, it's impossible to know what the problem is in your case.
Since several months (when we first added SODE jetways), KLAS requires GSX so, be sure you install it and it's working correctly. Best to install the latest version.
Already had GSX installed, but updated to the newest version to see if that may be the problem. In fact, the Live Update wouldn't run until the latest GSX was installed. So I did that, same problem.
As explained so many times on the forum, the correct procedure in relation to the antivirus is NOT to "disable" it. Instead, you must be sure the Addon Manager folder is added to the antivirus Exclusions, then run the FSDT Live Update again.
Did that as well. Tried it, and got the same result. However, I did notice one thing. When KLAS was originally released, the minimum requirement for it was P3D v4.0, which is what I had. Now, while I assume it is because of GSX and the later releases, v4.0 is outdated. I'm in the middle of a complete reinstall with P3D v4.3, and will see how that runs. Thankfully, the only addons I had were KLAS and KLAX, which I already had the registration keys and serial numbers backed up, so I really haven't lost anything. I'll report back when I'm done.
