Send the program log, it is located "C:\Program Files (x86)\FSrealWX_Pro\logs\fsrealwx.log". It would be nice to see a screenshot of the program window with the simulator running and the Interface bookmarks in the program settings.
So, as I said it seems OK for now. Pretty sure it was FXUIPC4. Dare I ask for a little advice then I'll leave you alone. If I uninstall and then reinstall realSX2Pro how will it affect my registration? Do I have to pay for V3? Thanks.
