Hi,I've probably missed something in the forum or manuals, but here's the situation:I have installed FS2Crew as described in the manual (I'm using FS9, with its own service pack, plus PMDG 1.3 and the 800/900 737's). I start with the Cessna, etc. and then load the 737, which is cold and dark.All the appropriate menus and submenus from FS2Crew appear and all sounds work properly, but many switches which, according to the manual, I should be using (not the FO), are NOT operational. For instance, I cannot switch on the battery, cannot start the APU, the CRTs stay dismally off, etc. The FA, FO and all other sounds are there, I can interact with them, but not with the plane itself.What am I doing wrong?Pentium IV - 3 GHZ HT, ASUS P2P800 Motherboard, Nvidia Gforce 5200, 1GB RAM, Windows XP HE with SP2 installed.Any help will be appreciated, as I have been enjoying the PMDG 737s for quite some time, in combination with RC.Regards,Giorgio

Hey,Make sure that you do not turn off the avionics switch in the cessna, the NG's don't have one.Hopefully it is that simple :)David

That's right, ensure the Cessna's Avionics Switch is "Off" when you load the PMDG from the Cessna.Also, what version of FSUIPC are you running?I installed the latest version of FSUIPC but had to switch back to 3.4 because the CRTs would never turn on.Also, ensure that you installed Service Update 1 for the PMDG 800/900.Some people who were reporting similar problems to you failed to install this update. The problem went away after they installed the update.All the best,Bryan

Yeah...I had to do the same thing. What's up with the new FSUIPC version anyway? ;)

Thanks Bryan and Co.,It's now working. I uninstalled all of FS9, re-installed everything again, installed FSUPC 3.4 and, hey presto!Thanks for the assistance. Now, er... I have a flight to fly! ;-))Giorgio

I'm also having the same problem as you but is there another way of correcting it instead of having to reinstall FS??? I';; try with replacing the fsuipc 3.4 with my current 3.411 but the problem is I don't know where it could be downloaded anymore. Could anyone help me out on this??thanksEien

You don't need to re-install FS9!!!!!Just copy FSUIPC 3.4 over the currrent version.Took me 10 seconds to do.Bryan
