Okay, so now I have Ep 3 saving properly, but Ep 4 does not recognize the save, looking through the earlier parts of the thread, I do have a folder in my c path/users/name/appdata/roaming/renpy that reads rebirthep3, along with ep2 and 4, and I also have the vamp folder.
Looks like the vamp and rebirth2 were last modified on 3.9.22 which sounds about right, and 3 & 4 show modified today 3.20.22
I did re-install rebirth 3 / v2, but I just loaded a save game, going to try to start v3 from scratch and see if that fixes it maybe, shouldn't be too long with the control key, I hope.
Edit: Okay that worked, just had to play v2 from the beginning, well hopefully this will help anyone else who runs across this issue.
