Since I installed the -800/900, by ovhd panel is useless. All switches remain off and cannot even be selected on. This renders my A/P useless since the flight control hydraulic switches cannot be turned on.Anybody experience this, please help?

Please read forum rules.

I'd suggest you remove whole PMDG with the uninstaller found on the PMDG website, and reinstall only needed files. Base + Updates.See then if it's working.If not, go step by step through the tutorial flight.If still doesn't work, then ask PMDG :-)

Silly question, but are you using FS2004 or FS2002?Best,Vin ScimonePMDGwww.precisionmanuals.comhttp://www.precisionmanuals.com/images/forum/devteam.jpg

Thnaks for the replies, but I found the problem. The gauage files were installed corrupted.I did a total reinstall, everything works fine now.ThanksCorey
