Usually a CTD is the result of
- a corrupt landclass file (= addon scenery)
- a corrupt mesh-file (= addon scenery)
- a corrupt BGL-file in one of your addon scenerys (downloaded airports)
- a corrupt gauge in one of your downloaded panels
The best way to find this out is trying to determine when or where the CTD occurs, if it is always with the same plane then it is most likely a corrupt gauge, if it is always over the same area it is addon mesh/landclass/downloaded airport.
I had the same problem ,it always happened over Sweden and Cyprus, after I deactivated the downloaded LCEN airport (Cyprus) and some downloaded Swedish airports and landclass files the problem was fixed.
I also had a problem with a DC10 panel, changed it for another and all okay again.
Hope this helps you, if not tell me.
