Missing gauges

I downloaded and installed P-38 planes by Copley. None of them had gauges. Panels ended up blank. Every model was missing gauges. They are beautiful planes and I would like to have them complete. Has anyone else had this problem with the P-38 models by David Copley. I downloaded and installed successfully about eight other planes and all the gauges worked except for the P-38's. I am using Windows 8.1 and have a loaded PC. Also, with today's session when trying to launch a newly installed plane, the PC would crash and then restart. After many tries, the plane would load properly and run normally. I have never had this problem before. I never had this problem before I tried Win 10 and FS 2004 would not run, so I rolled back to 8.1 I lost all my ad-dons. and had dozens of updates to contend with. So be warned about Win 10. Thanks for any help on these problems.
