Using FSX Gold, on a Windows 10 Platform, Predator Computer Lots of Memory etc, I seem to have lost all water feature displays they come up as land masses, Boats Ship are present but not the water itself. I have tried to adjust various scenery settings no help, Any ideas would be helpful, PLEASE. Recently Installed REX 4 texture Direct with Cloud Enhancement.
The combination of adding something new and your attempt at "fixing" it has screwed things up.
I would try to uninstall that add-on and then drop in disk one and repair.
Check and see if all is good then put in the add-on.
If all that doesn't do it the using the link below I would clean it all out and reinstall.
