Hello,
I am having trouble when using GSX while at your KIAH airport scenery. When I am about to pushback and do Ctrl + F12, then select option 5 for pushback, I get the following error message as seen in the attached screenshot. I've noticed this error at a couple of other airports but mainly in KIAH as I fly there a lot. This only happens when I'm at the E-gates. Now, I did do some changes for the pushback to take advantage of the push and pull feature when parked at the E-gates (I've attached the kiah.ini file as well). I've spent several hours creating new pushback from those gates. When I see that error message pop-up, I take a look at the log (which is attached as well) but I'm not sure what it is saying. Hopefully you can shed some light. Everything is updated too by the way.
