Good morning I have problems to install PMDG 737NG and PMDG 737-800/900, I've installed it from safe mode and then it works.The fs2004 system crashes when I select the aircraft, "flight simulator has encountered a problem and needs to close" and this error: A fatal error ocurredAppname: Fs9.exeAppver: 9.00.30612ModName: panels.dllOffset: 004867E What can I do? If I select orher aircraft and switches PMDG it works. Thanks and sorry for my english.Eva

Try deleting the one line in the fs9.cfg file that assigns the default flight to the pmdg aircraft. Use the opening menu to select a flight instead of using default flight. Your English is good enough, but the problem is confusing. Hope this helps.
