Hi Umberto,
I have installed GSX both versions. The question I have is I have the payware commercial-level MD80 it is a payware model as you know. My question is when I go to taxi the aircraft at Boise airport when I pull up to the gate and pull up GSX once I select jetways the jetway disappears or parts of it from some unknown reason. I have attached a picture below. I will also mention that I do have REX Worldwide Airports HD installed so I am not for sure if that is causing the issues. I hope I can get some assistance on this matter. I also wanted to add is GSX not compatible with the FSX commercial-level MD-80 aircrafts. Thank you good man and keep up the great work..
Edwin
