Really? Parked at gate B4 I get the following. Where the hell is JFKC Chicago airport helipad? This is after the reinstall.
I don't see anything wrong in your screenshot, and neither I see any reference in your screenshot to that JFKC helipad so, it seems either you posted the wrong screenshot, of you fixed the conflict caused by the other scenery, either as clearly explained on the GSX manual, or by removing the conflicting scenery.
The menus in your screenshot are perfectly fine, and they are they are supposed to be with a scenery, like O'Hare 2011, that has a YOUCONTROL menu in ADDITION to the normal GSX menu.
When a scenery comes with a YouControl menu, when you press what is really the YouControl Hotkey ( CTRL+F12 by default ), the YouControl menu will show, with the 2nd option being calling GSX. When a scenery doesn't have a YouControl menu, when you press what is really the YouControl Hotkey the menu will just show GSX.
Which is why, GSX has its OWN hotkey, ( by default CTRL+Shift+F12 ), which will call GSX directly, regardless if the scenery has a YouControl menu or not.
So, in your case, since you must have called what is really the YouControl key instead of the GSX key, the YouControl menu came, with GSX being option #2 but, since you haven't posted any screenshot of how the GSX menu looked like I can't possibly say if GSX is still reading the wrong AFCAD ( because you haven't excluded the helipads from another conflicting scenery ) or there wasn't any helipad to begin with, and you were just confused by the De-icing PADS at O'Hare in the YouControl menu.
On another note, after reinstalling GSX, My OHare scenery entered into a trial mode even though the addon manager shows the scenery installed and active.
If the Addon Manager says the scenery is active, then it is active. Why you think is in Trial ? Do you see the buildings disappear after 5 minutes ? That's Trial.
