Game not saving

I got planet of Lana two from KOYSO the auto save isn’t working. I played through chapter 1 to chapter 3, and then when I got off the game and got back on, it just took me back up chapter 1, like at the end of chapter 1. I’m on a Windows. PC I have a RTX 3070 and I tried to fix it by running it as administrator deleting and downloading the game again and I went to AI and ask about it and it the game basically has the auto save in the DRM and when it is cracked/bypassed it. It’s basically getting rid of or messing up the auto save file, but is the AI right or is there a way I can actually fix this? I don’t have any graphics glitches or whatever. and the site that I used I’ve got other games from it and they all work perfectly fine. And it has a good rating on trust plot to I just wanted to know if I can fix this or I can’t.
