Yea I would say spiel probably hit the nail on the head if your using vista there is a permission issue when the game is installed in the c:/public/games folder if you google it you'll find tons of threads with these problems not saving settings the only fix that I know of is to install it in a different place I simply moved mine to c:/programfiles/
But I wound up with an additional folder in a really weird spot forget where as it was a pretty long time ago, something like c:/local app/virtual data (show hidden files must be enabled to find this I believe) that had to be erased for my add-ons to run right and save my settings
Hopefully some of that might be useful
