Hi, sorry if im asking something that has already been answered. I've tried to search for similar topics but the ones i found were only about fatal errors while starting fsx/choosing the aircraft or just after installation. My problem appeared after maybe 10 successful flights on a new fresh install with only 3 addon aircrafts (carenado 150, lds 767 and ofcourse pmdg 747X. I got this problem today after doing a flight from VHHH to KLAX, while i was coming in on final and maybe 10 seconds after a/p disengage (under 1500 feet because of low clouds) the screen froze and i thought it would "get back" again but it stayed that way for maybe 20 seconds and after that i got the "FSX fatal error" (dont remember the exact phrase) it wanted to restart FSX after that but i canceled it, so i dont know if i maybe deleted an error log that would've come.Anyway my specs are as follows: Vista 64bit, FSX sp2, GEX/REX2, UTX, no custom scenery for KLAX except for GEX and UTX. FSUIPC 4.3 registered. I've also edited the FSX.cfg with the MEMFIX=1 to get rid of disappearing aircrafts. And thats pretty much it, reformated the whole computer when i got Vista 64 to get rid of the OOM's; so the OS should be pretty clean.Edit: I also checked the DLL.XML (correct name?) to see if something were wrong with it, but although it looks a little different it is identical to the advice about how PMDGevents, sound etc should be (<Disabled>false<Disabled>) on the three entries.Thanks in advance

I think it's an issue regarding CTDs after long flights. Don't know if there's a definite solution for this, but I think it has to do with settings that computers cannot cope with. Maybe a search for long flights will give you more results.

read the sticky about missing textures and try the highmem tweak for your fsx.cfg file. Also I suggest disabling DEP in windows

He does say right there that he has the HIGHMEMFIX line in his cfg...

What do you mean by "DEP", whats that? :( Also i read somewhere that people would get problems on long flights because of switching windows/menus or something like that, may this be the problem?Something i forgot to tell you was that i had saved the flight when i was about 500NM away from T/D and it was after i had loaded the flight again that i had this problem so i hadn't been "flying" for so long. Or maybe that doesn't matter.Thanks for the replies

http://www.vistax64.com/tutorials/65790-de...f-programs.htmlGot rid of crashing on approach to scenery for me

Yes, i have gotten the popup about Data Execution Prevention when FSX has crashed sometimes, should i disable DEP for everything or only for FSX?EDIT: i have Avira Antivir (freeware version) and Lavasoft Ad-Aware (also free version) does these suffice for DEP disabling? EDIT2: Strange i don't seem to be able to turn off FSX.exe in the: "turn on DEP for all programs and applications except for those i chose" (translated from non-english vista 64, so the name might not be entirely correct) Was this what you meant David?

You need to disable it in the command prompt, follow thishttp://www.vistax64.com/tutorials/120778-d...le-disable.html3. To Disable DEP - A) In the command prompt, type in bold belowand press Enter. (See screenshot below) bcdedit.exe /set {current} nx AlwaysOff :( You should get a success message back. C) Close the command prompt. D) Restart the computer to apply.
