No mods. I've never used any at all. I've only recently, within the last few days, gone looking for them. Until now, I've always played the game in its original form. Perhaps I should mention that the version of the game I'm using isn't a legitimate version. Believe it or not, I did actually buy the game, back when it first came out for PC, and as I always do, I made a backup. At some point, my original disc and case were stolen from my apartment, so I had to find a fixed .exe file for the backup, so I could continue playing. I have no intention of paying for a game twice. But, might that be the cause of the problem? I can't really see that being the case though. See, another thing that I neglected to mention in my initial post is that the saved game files that I downloaded from here aren't the only ones that don't work. I also had 3 saved game files of my own, in My Documents, from a prior installation of the game. Long story short, I had to format my HDD, so I backed up My Documents and all my other important stuff, formatted, and then put everything back where it was. None of those saved games will work either. And those saves were created using my copy of the original, with the fixed .exe, as well. No difference between the installation then, and the installation now.
