EDIT:
I tried it on a different computer (same OS) and I can't replicate the problem, so somehow this is happening on my end. I do have an older game and that game does have the files being referenced in the errors--I believe the load feature is somehow looking in the wrong location for the saved game, and trying to load a saved game from an older game.
Edit 2:
OK, this is driving me nuts. I install the game into a new folder. I run the game, select my options, and when I have the option to recruit, I choose to save the game. I can't save, it gives me this error. It makes no sense. Why would the save feature even be looking for a graphic, let alone a graphic from a completely different game? I'm guessing there is some errant registry setting or something, but I'm not finding it.
