Problem when loading saved game

[Castellon]

THe only files in the save game folder are saved games. THe default files are 3 autosave files, then 2 files for every save game you have. Even if you deleate the autosave one If you have autosave on they will just be created again so I don't see any harm you could do by just deleteing files form the folder.
Do you have any mods installed or have you edited any files yourself?

Since the error gives you the line number, you could always go in with a text editor that displays lines and find what the trouble is.
