Hey Zembo!
Sorry you're having issues with the game. You could try backing your saves up and doing a complete fresh install.
Locate your A House in the Rift folder > Game > Saves and save that folder to somewhere else.
Navigate to "AppData\Roaming\Renpy\AHITR" and delete that entire folder. (You could also back this folder up if you don't have the saves folder in your AHITR directory).
Download the latest free version from our Patreon:

Once installed, boot the game up and just make a quick save. Close the game down and the saves you made a back up of, drop them into the new, freshly installed game directory: AHITR/Game/Saves
Let me know if that helps!
