CTD World Update 4

Is your flight sim crashing after world update 4?

ok try this as this worked for me and other users 

Uninstall FSUIPC then download the latest version from fsuipc.com when installing it make sure you untick the option where it makes FSUIPC start with msfs. 

Now launch msfs, load into an airport then launch fsuipc. If that doesnt work we will need to wait until asobo fixes this. They are working on it now.
