For anyone having trouble with the save not working or not saving at all, this worked for me
1_ Create a New Folder in Desktop
2_ Backup the old config.ini and save.ini files
3_ Rename the remain files in the main folder without using special characters
4_ Move them into the New Folder
5_ Run the .exe
7_ Start a new game
7.1_ Press Space
7.2_ Go to lab
8_ Save the game in the computer on the left side of the screen (This should generate a new save and config folder)
9_ Paste your old config.ini and save.ini
10_ Enjoy the game
