Hello everyone
I know its weird replying to a 10 year old thread, but I installed WOAI yesterday after deleting it because it used to crash my sim.
I made a clean install of FSX and installed WOAI over there, and set the aircraft quality to Medium High, So far I haven't had any issues with FSX crashing at all!
I guess my best preference is to set the aircraft textures in settings lower than ultra high if you don't want fsx to crash.
Stay Safe everyone!
