Step 1. just like above, go to the folder you have the game at where you open the game to play it. Should look similar to this:
Open up the game folder, then open up the saves folder. Then delete everything there (move it to a backup folder just in case something messed up).
Step 2.
Now, open up a new folder on your computer somewhere, doesn't matter where. Go up to top where it shows your current folder path and click in the blank space inside that box. The picture below shows where to click, just see like where the arrow is in the picture.
It'll look something like this after you click on it.
Now delete whatever text is in that box with the backspace button and put this instead:
%HOMEPATH%\AppData\Roaming\RenPy
Which will look like this:
Hit enter, and you should see folders with each of the RenPy apps you have saves for. Should look something like this:
Find AWifesPhone_0_5 and open it up, it might say _0_6 or _0_4 or even a different number who knows.
Delete (or move to a backup location) any saves that you want to delete. Deleting everything in this folder will not break the game, but it will delete all saves you have for the game as long as you also deleted the saves in Step 1.
