These steps can be used for Troubleshooting Prepar3D with Orbx Scenery Installed

This video shows how FTX Central will activate the Orbx Scenery again even after both files outlined have been manually moved or deleted. FTX Central will Organize and layer the Orbx Scenery correctly when launched.

Note: This action will disable all Non Orbx Add On Scenery, However the Scenery that is being launched from the "Prepar3D v4 Add Ons" folder in the PC > Documents location Will Not be effected.

I have also Included additional notes in comments below the video

Uninstalling & Reinstalling FTX Central is the first troubleshooting step to take if FTX Central is crashing, wont launch or not working correctly.

Note: This Will Not effect any of your current Orbx Scenery
