Cannot load savegames

I cannot load one of my savegames. Always when he want to load the policies, he closes the window. Do I need a speciall programm to load the savegames? Or what is the error? Thanks for help.

Hi. the game writes any errors into a file called ‘debug.txt’ inside it’s ‘debugdata’ folder. if you email that file to me at cliff AT positech dot co dot uk, I can take a look at it.
If you have installed any mods, and then uninstalled them, this can cause problems loading save games. This is also true of very old save games from older versions of the game.
