@TatsuDragneel; Ok, so you say you aren't using any mods. But that error message indicates that the save you're trying to use was made while you had at least one installed. (Or possibly a patch that is now not installed.)

Open the file(s) "package.mft" with any ASCII text editor and increment the version number by 1. Rinse-Repeat until your save loads.
[NOTE: It may be hard to tell which of the (potentially) many "package.mft" files you'll need to adjust, but take things slow and you'll figure it out.]
