So I bought UT this morning and in the instructions is tells me to delete Traffic030528.bgl in the C:Program FilesMicrosoft GamesFlight Simulator 9SceneryWorldscenery directory.There is no such file. Only Traffic030528.utb. So what should I do here? Why is it having me delete this file anyways?Thank you,-Allistah

the .utb extension means ultimate traffic renamed the file so that it would not be used. The traffic030528 file was originally your default FS9 AI traffic along with all those wonderful fictional airlines such as Landmark and Orbit.Since UT increases traffic so much, and there are only so many parking spaces, (even with the added UT AFCAD files), UT suggests that the traffic030528.bgl file be removed.Since it is renamed .utb, it will not be used by your computer, so you can keep it there if you like. Should you wish to restore your default traffic, simply change the .utb to .bgl and all the Landmark, Orbit and World Airways flights will return.

Ah! Makes perfect sense. Thanks so much! :-) I'll just leave it there.
