First I wish to thank once again the community for such overwhelming support, and the feedback has been extremely positive.

We have just concluded a small update on some issues:

No need to uninstall V4.0 for installing V4.1

Fixes:

1- Jetways connecting more perfectly with terminals.
2- PAPI lights not visible (FSX version) corrected
3- Static aircraft replaced with newer library (courtesy of DRZEWIECKI DESIGN)
4- Service tunnel fix (P3D version)

please re-download the installer and just run it again. Like mentioned no need to uninstall
