Having played with this sim for over four weeks with no problems I recently experienced CTDs when trying to load UK airports. These problems lasted for two days then mysteriosly solved themselves. I have just noticed the latest "known issues" on the MSFS site which might explain why:

Crash when flying some parts of France and Northern Europe

• Workaround: Deactivate Bing Data World Graphics 

I just noticed a similar issue with certain airports/regions in the US as well.  Haven't been able to load KSBA, KBUR in California and KORL in Florida.  Northeast seems to be OK.  Will give this a try.

UPDATE - sadly, this did not solve the problem I'm having. CTD right after starting the flight - this time in KMRY.

There seem to be a multitude of problems and a multitude of fixes depending on each cause. It seems a shame that there are no fully explanatory crash reports to help us, the current ones are just too vague to be of much help.

It appears that the cause for me was running the beta Navigraph data.  I uninstalled that and the crashes disappeared.
