I installed world of ai after I bought Weapons. Now, all of the weapons traffic is gone. I would like to keep the World of ai, and still have the CS intuders. Any help? Thanks.

World of AI is FS9 native AI scenery, whereas I suspect the CS intruders are FSX AI scenery. The two are incompatible; if you run an FS9 AI scenery inside FSX, it will cause the FSX AI scenery not to run.

Perhaps you could convert the World of AI flight plans into the FSX format using something like TTools (a Herculean task) or perhaps you could convert the CS intruders into an FS9 formatted flight plan.

Either way, I don't think there's an easy solution that doesn't involve decompiling, modification of a source file, and recompiling.

I use AI Flight Planner (AIFP) that comes with a handy tool to convert FS9 to FSX flight plans, as the way FS reads the plans is different between the 2 versions. Although WOAI packages may install correctly to FSX, you still need to convert their FP's, if not all traffic.bgl's will not show.

I have no Idea how to convert. Let's try converting the CS to FS9 format. ALthough, when I install ai packages, it says choose between FS9 and FSX.  :(
