Well I wish I could go back to the previous version of GSX before this last update.
The current version is FAR better, ESPECIALLY the FollowMe.
Now I have to chase the follow me vehicle, sometimes it makes sudden you turns, and then disappears, leaving me in the middle of nowhere
The Follow Me doesn't disappear. If you see that maneuver, it's because you went too close to it, so it tried to escape by turning around you.
This never happened with the previous version
It was a bug in the previous version, in fact. You could smash into the FollowMe, and it wouldn't do anything to save itself...
When I hit just "warp me there", it brings me to the middle of a ramp with nothing around.
This doesn't have anything to do with the current version, it's just that the wrong AFCAD is used, and there surely a reason for this.
Is there anyway to install the previous version?
No, because the current version works, and nothing in your report seems to indicate a problem with it. If you have a problem with the wrong AFCAD used, everything in GSX will not work (or, more precisely, it will work correctly for *that* AFCAD, but it won't match what you see on screen, so you will think GSX is "wrong" )
I looked at the AFCAD data that GSX is using and it is using C:\mytraffic professional\mytraffic\scenery\BRr2_ whatever airport I am at
Are you saying (literally) that you always see the SAME filename BRr2_ (and NOTHING else), or are you saying that, for example, if you are at KLAX, you see the BRr2_KLAX.BGL and if you are at KJFK you see the BRr2_KJFK.BGL ? This was just an example...
And, you don't say WHICH airport you are referring to. If the airport is a 3rd party airport, with its own AFCAD, you must ensure it stays on an HIGHER level than MyTraffic.
This is a general rule in FSX and doesn't have anything to do with GSX: 3rd party airports must usually be on top of everything else.
My traffic is the 20th scenery listing down from the top. All the upper sceneries are UT sceneries for USA and Europe. Is this normal?
If with "UT" you mean Ultimate Terrain, then no, it's surely wrong (unless you only use default airports), see above.
