Sorry about that! Actually, on Windows, there's another place where the persistent data for the game is stored other than the main folder. If you still have access to that other computer, you can find it under this file extension: C:\Users\[Your Username]\AppData\Roaming\RenPy. There should be an "OurLife" folder in there, and that has all of your progress data. Hopefully that helps, and thank you for playing!
