Dear Sir,I have just installed the PMDG NG and 800/900, however, when using the 900, when I turn the panel lights, the panel is not viewed properly, for example, some warning lights go off, such as the drive warning light. Also, when starting the APU, although the low pressure light goes off, the APU EGT indicator does not move. Do I have to uninstall and install everything again? An early reply will be greatly appreciated.ThanksIvor

Ivor,Without any further information my best guess is a corrupt install. I would remove the NG by using the removal tool available at the PMDG site and then install the NG fresh.Hope it helps,

I have uninstalled PMDG and installed it again and everything is working perfectly. ThanksIvor
