FSX Military AI works and default traffic problems!

So... I use MAIW traffic and I want to remove the default "Orbit Airlines" and other terrible airlines... using the traffic sliders affects the MAIW traffic too, deleting the traffic BGL crashes the game and WOAI overrides the MAIW traffic too... how can I fix this? I would prefer to only have GA traffic, but if that has to go too then so be it!!

Thanks!

NOTE: If I install UT2, can I still add in this MAIW traffic??
