Impaler - Yes, your "split" map is due to the CA.ini resolution change you made. I made the same mistake a few months ago, and resetting it back to the original values fixed the issue.

Rene - Your hat switch is likely set up as POV. As such, it will control your head movements in virtual cockpit and TADS/radar azimuth in the static cockpit.

Your problem with only being able to load an NTC mission is likely due to your discs. You can either mount the discs as virtual drives or make copies of the discs (which corrected the issue for me).
