ERROR (please help)

I get an error when the game loads. It says -
“Missing Global Variable:. \SIM_GlobalVariables.cpp 40”

Now this was after I went to “http://www.positech.co.uk/support/index.shtml” to fix the display issue.

Thanks

Are you sure you haven;'t installed any mods at any stage? this is the most likely cause (a mod that doesn’t work correctly, or from an older or newer version).
