So on my first run of the game today I was able to open PG on mission editor as well as fly instant action without any issue. After exiting the program and starting it up again we're back to CTD on mission editor or instant action if PG is chosen as the map. Again Caucasus has been working without issue and also that the above problem has been occuring with any aircraft not just the F/A-18. I've attached the log from the successful run as well as the unsuccessful run. Again looking at the logs the problem seems to occur at this point
Now, this file doesn't exist in the directory in this form but as terrain.cfg.lua.dll.crypt which I assume is decrypted by DCS when needed by the keyless DRM function. So again I am suspicious something is going on within this system that is causing our issue. I can also report as Riskyflier did earlier that I had success once by deleting terrain.cfg.lua.dll.crypt and repairing but that similarly to how he described it only worked during that one launch but could not be replicated on subsequent launches. Hope some of this will be useful.DCSlogs.zip
