Im am suddenly unable to enter GW / Fuel and ZFW into FMC by clicking on the correct buttons. I use PMDG 737NG 600/700 with WindowsXP SP2 GDI-Patch and MS FlightSimulator2004 V. 9.1 and FSUIPC 3.4 unregisteredMy PMDG used to work correct some time ago but know it's unflyable due to the problem that there's no way to enter the weight and amount of fuel. I tested reinstallation but it didn't help anyway.Any help would be appreciated.THX BjI apologize for any mistakes in language as i'm not a native speaker.

Mr THX Bj,(Please take a minute to re-read the forum rules. You are supposed to sign your posts with your real name.)Sound like a peculiar one. Maybe you should send [email protected] a mail and ask for some assistance.Hope it helps,

I'm sorry for having violated the forum rules. I guess i have to admit that i didn't read them thoroughly enough. I made up for it now.I just drooped PMDG some lines concerning my problem. I hope they can help. It's very annoying not to be able to use this marvellous addon.Thanks anywayBenjamin 'Bj' SchmueckerAs you can see I'm a learning individual ;-)

Benjamin,Can you enter the corresponding values manually? I know there is a feature of PMDG that you can press LSK "whatever" to let the software automatically populate these values by doing simple math, but as far as I know there is no such feature on the real Lady. (someone please correct me if I am wrong, I am a learning individual as well ;))So can you do it manually? If yes, then it should not keep you on the ground. While I admit that it's rather annoying if a feature stops working after a time..Cheers,

Well, it basically is possible to enter the values manually but I am not quite sure which unit the PMDG uses. I tried to enter the value MSFS displays and got an 'Invalid Entry' Message in the FMC.Anyway that's not the way the product is meant to work, even if real pilots have to enter the values manually.Benjamin Schmuecker
