Themis,
Do you have add-on sceneries or AFCAD files for Greece? I know there was an issue with some add-on sceneries that caused crashes in this part of the world... I have Hellas Scenery Project (HSP) Greece and I think this suffered from these problems when first released.
If so, check the readme file of this scenery for the designers website and check it for updates or patches. Or, if you can remember where you downloaded it (avsim?), check there for more recent versions.
If not, crashes can be caused by faulty AFCAD files (the airport facility files that start "AF2_" then the airport's ICAO code) and the only fix for this generally is a different version.
Or failing that, any add-on landclass files (the ones that determine whether the land looks like fields or a city as you fly over it...) - if you have these check the landclass folder to see if there is a texture folder as well as a scenery folder... Landclass sceneries must not have a texture folder as this causes memory conflicts and crashes.
I hope this helps you, if you aren't sure what I mean or this doesn't work then post again and I'll try something else...
Good luck!
