Are there any error messages when you attempt to save?

[Eddi]

you cannot save if the directory is write protected. this can happen if the game wants to save in the "Program Files" directory directly, instead of the user documents directory, because somebody put the openttd.cfg file there. delete that file, and the game will reconfigure to use a proper personal directory
