Yea, I got you. I'm gonna give a full rundown, just in case if anyone else needs it. First, you have to download the API steam replacer thing that I quoted in my first comment, you can find it on this page. Don't mind the weird ass name, I just left it as it is cuz I don't really care, but you can change it if you want to.

Next you have to extract the file, which is pretty simple. All you have to do is click on it and there should be an option to extract it at the top-middle of your screen.

Just follow the steps to extract it and you'll get a file that's not compressed(just make sure it's not compressed, it will tell you if it is under "type" like in the image above.
I moved the extracted folder itself to the college kings folder, don't know if you NEED to do that, but I did.
Click on the folder you just extracted (the "updated lib for 3.1.8" just to make sure we're on the same page) Then click on the "lib option" (don't double click it just make sure it's highlighted). Then copy it.

Once copied, back out to the main college kings 2 folder and you'll see the main "lib" folder. Click on it (just highlight it) and go to the paste option and this should pop up. It might not look the exact same since I already did it, but as long as it's there you're on the right track.

Then just clip on "replace the files in the destination" and you should be all set brother! Load up your last save file and it should automatically continue on with the story. I hope you're using Windows, cuz I don't know how to do it through mac and shit. Let me know if it doesn't work for some reason.
