Now it work´s , but i have 2 Jetways there? How i remove it?
Have you followed the video tutorial posted at the top of the GSX support section ?
It's made precisely at FlyTampa EHAM. Basically, you must start by excluding an existing jetway first, exit the sim, compile the exclude file with the GSX Control Panel, restart the sim, and the original jetway will disappear.
IF you downloaded a pre-made customization file, it's enough entering the customization page, and change anything (clicking twice on any one Exclude checkmark), will be enough to have the exclude XML source file to be recreated from the exclude areas in the .INI file you downloaded, so you can compile it.
