I've had the SSTSIM (Concorde FS9 add-on) for quite some time now. My old computer became really tired, and for about 3 years, I couldn't even play flight sim because the computer just couldn't handle it. I recently got a new computer that will run flight sim flawlessly with complicated addons, and I've successfully re-installed some (but not all) of my flight sim addons. Fortunately, I was able to install the Concorde. I've been having fun with it, but I've had one major problem: I didn't recover my manuals, and can't remember how to transfer fuel to adjust the CG for supersonic flight. (I used to know how to do it, flawlessly.) Every time I try to fly it, about 30-45 minutes into the flight, the number 3 engine will shut down completely. That's not to mention the M/CG annunciator that chimes every time I approach Mach 1.
I think the 2 issues are related. If anyone has this sim and can offer a remedy, then I'd really appreciate it! Thanks.
