After a few problems with FSX I decided to sort them out which involved a few textures that were missing, I then corrected these problems, launched FSX and selected the PMDG 737NGX WL. FSX then loaded up as per usual until I got to the cockpit itself and then the aircraft did a front flip and landed nose first into the runway. This happens at every airport and every variant of the PMDG 737NGX. If anyone knows what is going on please post a response!
Thank You
