As mentioned above, I would suggest downloading the World of AI GA packages - I think they're up to 7 now?
If you're interested in bringing back the fsx GA and not Orbit or World Travel, you can always download
http://www.flightsim2004-fanatics.com/u ... _GA_DL.htm the fsx GA only files.
By Traffic X are you referring to UT? Or Traffic 2007? Is Traffic X an fsx compatible only program? or is it also compatible with fs9 AI?
If you want the GA packages listed above to be 100% "fsx" compatible you'll need AIFPC to convert the Ttools flight plans.
