Hey! Thank you so much for the help. I re-downloaded XP11 from scratch to try and solve the issue, so I currently have no plug-ins installed. It doesn't seem to fix the issue so I was wondering if I was missing a plug-in that was causing the plane to load incompletely. I installed the latest OS and it keeps sending me security warnings when I load up the 737ng, but I simply override the warnings so I'm not sure that is the problem.
It's odd since I have the 757 and a350 paywares installed and they run fine with my graphic settings and don't load with missing parts.
