Generally, I've had no problems with the 600/700 till tonight. I did a search but didn't come up with anything. My previous flight was from KSFO to KPHX. I saved the flight after finishing.Tonight I reloaded the flight and all seemed well except I couldn't load any fuel. The FS9 menu accepted my fuel changes but when returning to the cockpit it would revert back to its previous setting. Has anyone else had this problem?Specs:Win XP Pro512 RamP4 2.66Nvidia Gforce T4800/omega 4345 driverPMDG 600/700 onlyFS9

Lamont,No fuel loading is permitted when engines are running and sim is not paused! ;-)Could the above be your problem?Hope it helps,

Hey Mat, no engines dead but apu running and sim not paused. I'll try loading with cold and dark cockpit and sim paused and let you know.

Mat, pausing did the trick. Thanks.

I don't know if this is relavent but it is rather funny so here goes. Quite a while back I was setting up for a flight from KCRP and found that I could not set the proper amount of fuel in the tanks. No matter what I would do, the minute I would return to the cockpit the fuel tanks would be completly full again. I spent two days trying to figure out why the plane couldn't be refuled properly.Then I realized something. I was always starting with the plane at the exact same parking spot. It turns out that this spot was immediately adjacent to the fuel pumps at the airport. I moved the plane away from the fuel pumps and then I could put any amount of fuel in the tanks with no problems. Needless to say, I felt rather silly :-doh

Been there, done that and yes you definitely feel silly. My problem was the reverse I couldn't load any fuel. But as I said in my previous post pausing the sim worked.
