FSX crashes after a short amount of time after installing some MAIW AI Packages

OK, but leaving the traffic file will not cause the error. It will just not find the aircraft that the flightplans are for.
Only effects that are attached to aircraft/scenery cause the error.

So now that you have everything cleaned out, does it crash at the checkpoint?

Cleaning out the leftover files stopped the crashing.

OK. So we have established a good point. So now re-download one package, and by all means make it a package that you know uses that base where you have the issue.

Re-downloading should remove the possibility of a corrupt download.
Install that one package, and make no other changes, and go to the checkpoint, what happens?

After testing, I've finally found the file causing the crashes.
It's Traffic_MIL_US_USMC_PENDLETON_KNFG_HMLA-469_FSX

[Firebird]

The traffic file causes this or an aircraft in traffic file?

What happens when you load the traffic file into AIFP and validate it?

I have double checked my system and I get no errors BUT that is using the FS9 version of the package(s).

So I guess my next question is whether you have installed the AH-1Z and UH-1Y packages to go with the Pendleton package.

[JoeJeepWrangler]

Pretty sure it's the file itself
I got all of the required aircraft, as they showed up fine before the game would crash.

OK in which case what I would do is use AIFP to create the 3 separate txt files, and then compile those after checking that there is no errors when opening them in a text editor.
See if that makes a difference.
