For the people who are having problems with P3D shutting down, random CTD with the new Airbus 1.3.0 update, I ran into the same issues, but have found the solution. During the course of P3D 4.X development, I have been updating the Client and Content from my initial purchase of the 4.1 version to 4.5. Once I updated to 4.5, and installed 1.3 version of the Airbus narrow bodies, Pmdg NGXu I started having random CTDs. Removing such planes and returning to 4.4 was fix. After consultation with Lockheed Martin's Prepar3d forums, I was instructed to delete my shaders folder, P3D.cfg and update my Nvidia drivers. Apparently, P3D 4.5 Hotfix 2 has several changes under the hood that make it incompatible with the older shader files and cfg. Aircraft like the AS Bus 1.3 and NGXu that are complied using the 4.5 SDK make these incompatibilities worse and cause stability issues. Older aircraft compiled with the P3d 4.0 SDK show none of these issues/instabilities.
