Please look at your purchase receipt – the Serial Number is in big bold letters and starts with “CONCORDEX-” for FSX versions or “CONCX-P3D-” for P3D versions. If you don’t have your purchase receipt in your email inbox, double-check your spam folder. If you’ve lost or can’t find it, visit the eSellerate Store support page to have it emailed to you. I really dont know whats not realistic about that. I heard that the Concorde-X product requires activation. The addon is called FSPassengers as it simulates passengers aboard. You shouldn’t have to do anything to activate your Concorde-X product – the activation mechanism should be transparent to you as long as your computer is connected to the Internet. If the Concorde-X loads properly and you can fly, then you can be assured the activation has already taken place. I get an error “loading CIVAC.gau” and then the sim closes. Why?Īs per the instructions in the manual and the readme file, you need to install the SimuFly CIVA-C freeware gauge. You can find and download it clicking this link. The difference is night and day.If you want every flight monitored for passenger. My computer crashes when I first run the Concorde-X. PaulYorks said: Have to disagree with Hirgab.FS Passengers (FSPAX) is one of the best addons for FSX, especially if you like the big jets.Search here for some of the details, but frankly comparing it to XPAX is like comparing the PMDG 747 to the default FSX 747.
