Well, I've experienced second to none support from VRS and as far as I understand FSX configuration file isn't VRS responsibility, is it? There are many forums on FSX, you can ask FSX related questions there.
Problem is that many people want just jump into Superbug’s cockpit and instantly become aces there. As with real a/c it won’t work with VRS F-18E. You need a lot of practice, patience and studying to master Superbug.
