I had this issue with NGX for two days. I uninstalled all my PMDG aircraft and reinstalled them one by one. It was interesting to note that on reinstalling the installer informed me that there was a problem with the MS Visual C++ 2008 redistributable and offered me the opportunity to repair the files. This cleared up the issue and I am now zipping around problem free with this great aircraft. I presume that if you did not wish to uninstall the PMDG aircraft you could use the control panel uninstall programs option and try each MS Visual C++ 2008 redisributable file in the list and carry out a repair option if offered. My system has eleven listed and I do not know which ones PMDG use. I hope this will help some of you resolve your issue of "Fatal error" on loadiing thre 737NGX or for that matter any of the PMDG FSX aircraft.
