The only cause of crashes we know of is related to other (freeware) DLC and then mostly repaints of default aircraft and the latest Nvidia drivers (but that is sim related and not connected to the DLC).
If the sim worked and stopped working at a certain moment, it simply has to be because something changed. Keeping a simple logbook of what happened to your system is something I would advise every simmer.
