The old 737NGs install an old version of FSUPIC.This may be the cause of your problems...

Dunno what to say except that the Level D, if you uninstall it, goin' to ruin your PMDG md11. Somehow they are connected with with, something i gues. Maybe someone from PMDG or Level D can explain that better than me.

Here's the answer. Found this comment from Brian York on the FS2Crew Avsim forum:Special reminder note:If you re-install the PMDG 737 aircraft, the PMDG installer will overwrite the gaugesound.dll with an older version (different from the one the non-FS2Crew 2010 versions require).So, if after re-installing the PMDG 737 aircraft itself, you're finding that your FS2Crew enabled Level-D 767, ATR, PMDG 747, etc., are crashing, it's because of the old version of the gaugesound.dll that the PMDG 737 installed.The easy solution is to run the FS2Crew Start Center and click the button that says "RESTORE GAUGESOUND.DLL".That will re-update your GaugeSound.dll with the required FS2Crew version.Again, this only applies to FS2Crew releases prior to the 2010 Voice Commander versions.Cheers,Bryan Yorkwww.fs2crew.com
