Hello,
I've had GSX for a few years now and absolutely love it! It's definitely a must have for me. However, I've just come across my first hiccup with the add-on. I recently bought the PMDG 747-400 for P3D v4.2, and I can call in ground support from the air on approach to my destination airport, but at my starting airport I can't get past the YouControl menu. I've done both the key bind and clicking through the menu bar, and when I do either one nothing happens. It's only with this specific plane, the NGX and TFDi 717 both work perfectly with GSX. Any help is appreciated. Thanks!
