New feature (moving vehicles) working fine.
What do you mean with this ? What are the moving vehicles ? The new feature is an interactive scenery customization editor, there aren't any new features, and GSX always had moving vehicles. Please, be more clear.
I have updated Couatl, GSX. It occurs to me that in Key mapping window are Park me and Global. Not key for GSX.
This seems to indicate you haven't installed GSX. If you run the Addon Manager installer, when there's no GSX installed (for example, after uninstalling it), it won't update GSX.
So, again, try first to download and install the most current version of the Full GSX installer, and install it.
