Missing GSX in P3D

[Zimmerbz]

I have been on about a 3 week hiatus.  During that time I have made no changes to my setup.  My last flight I loaded, I noticed that I didn't have GSX as an option in my menu bar.  It was completely gone.  I also noticed that when flying from KLAS to KSLC, all of the terminal buildings were missing at KLAS (not KSLC) but the airport scenery in general remained the same.  For the record, I am using P3DV4.2 and the scenery at KLAS was FSdreamteam.  Keep in mind, I made no changes and the last flight prior to that things were working well.  Any ideas?

The problem of missing menu items under the Addons menu it's usually caused by one of these:

1) Defective antivirus. Download and install with the Antivirus disabled AND configure the antivirus to exclude the whole Addon Manager folder from scanning BEFORE starting the sim.

OR

2) Missing/Corrupted VC++ libraries in your system. See solution in the "Addon Manager not showing up in P3Dv4 **SOLVED**" thread:
