Repeated terrain.dll errors

[cavity]

I was wondering if anyone could help me figure out what is causing my problem.  I keep getting a crash and reported error message that says terrain .dll. I have deleted the fs9.cfg and let it rebuild, have uninstalled then reinstalled the update, and have run out of ideas as to whats causing it.  It happens randomly, at night or day, in places all over the globe, and after 5 minutes, or sometimes many minutes of flying.  I only have one mesh in Alaska, but it doesnt matter where I fly, it still happens.  Short of reinstalling, are there any other ways to figure out what is causing it?  No report comes back from MS when I send it, and dxdiag reports no problems.  I will have to quit flying because it is miserable to start a flight and then, boom, its over.  Todd

 I would start by removing the Alaska mesh and see if that stops
the crashes. I seem to recall having a problem a long time back
with some Alaska mesh and/or scenery...can't remember exactly.

It doesn't seem to matter where you are flying in FS9. Bad scenery
files somehow manage to get loaded and cause problems.
I recently had a spate of "Your computer is out of memory..."
errors. These were occuring in my "FS9_USA" installation of
FS9...I have 4 seperate installs. My "FS9_Europe" install was
working just fine. The only thing I had added recently to the
"USA" environment was a scenery package for the San Francisco
area which only had SUMMER textures. Seems that the lack of
the other seasons caused a memory leak and thus the error.
The errors happened even when I was flying on the east coast.
Disabling that scenery cured the problem.

So, errors can occur from the most illogical sources....

 Hope this helps you or others....

Thanks for the help.  I do have some add on airports that I deleted from the scenery library to see if that helps.  I just flew a 1 hour hop without  problems, so well see.  It was happening long before the Alaska mesh so I dont think that is it.  It will probably happen again, so Ill keep trying to pin point it.  Can afcad files cause such problems as well?  Todd

I've never traced a problem to an AFCAD, that I can remember,
however that's not saying that they can't cause BSOD type
problems. Most of the problems I've tracked down or read
about on the forums stem from bad .BGL files or missing/
corrupt textures.

Also, rather than delete a scenery element completely,  you
can just disable it in the scenery config screen, restart the sim
and go from there. That way you can re-enable various elements
one at a time to try to find the culprit.

I had this problem with Fs genesis roads,rails, lines, streams or whatever its called lol, I got it most everytime I started fs9, Mine would load to were it said loading terrain then pop up comes the error. I emailed them over there but didnt get any real info. So I reinstalled xp not for that error  ;D but other reasons. When I installed fs genesis agian I copyed the terrain.dll and after installing the roads rails, I put the original .dll back I never had a problem since.
