Thank you for such a quick response. After uninstall SDOEs, GSX installed but no courtl was shown in menu. also my FSDT sceneries are in a "trail mode" plus buildings etc are missing even in the trial mode. Using my code for verification no longer works. Does this mean I may have to uninstall all FSDT sceneries and reinstall again? One final note, during install of KCTL saw message that stated "error 2 running C:/program files (x86) addon manager\tidy.exe which mean system cannot find file specified." Sorry for the mess I appear to have.
Appreciate any help.
