It means what it says: "Run gsx level 2 control panel to patch sceneries with default jetways". Not sure how this could be expressed more clearly, but I'll try:
- Open the GSX Level 2 Control Panel, which has an icon on the Desktop placed by the GSX installer so, unless you removed it, it's surely there.
- Wait for the sim to close. If it's not, the GSX Control Panel will tell you.
- Click the "Disable default jetways" button, so the GSX Control Panel utility will patch the default scenery to disable the default jetways, which was originally done by the installer but, we surely don't want to run the installer *just" because after updating the sim the default jetways came back, that's why the GSX Control Panel has this feature.
