FSX atc.dll, ntd.dll and window.dll error in short time

[FoxMulder1982 1]

Hi all,

I have not had problems with FSX for a long time. This weekend I did three flights and each time I had CTD with another cause: first atc.dll, second ntd.dll and finally third windows.dll.
Is it normal that in three days I have CTDs of different genesis?. In principle, I have not changed anything in FSX for a long time: I added only the AI plane from TFS A343 and painting to it: In fsx.cfg I have only hightmemfix = 1 and affinitymask = 14 (according to the recommendations to AS16) I also use the bufferpools = 0 entry.
Fsx is very surprising works flawlessly many months and suddenly crashes three different errors in three flights. All this took place at the arrival to the destination airport. In flight I use only a few sceneries and I use only the scenery that I use for a particular flight.
I read on this forum about solutions to these problems but it is surprising for me that they have occurred for various reasons.

since  you  stated  that this  has  only  occurred  since  you have  added the  a1 plane   so suggest  this  is the  reason  for  it

The AVSIM CTD Guide, starting on page 32, provides some suggestions to fix.

The problem may have been textures for tfs a343 in .dds format. I threw in bmp and so far I have no problem.
It's a bit weird because from what I've read the dds format is dedicated to FSX - I also reduce the texture size to 1024 with mipmaping to not load too much VAS and I have a better FPS

Thanks for Yours help
