Thanks..yeah I initially did read it but I only deleted the file from app data folder not from saves folder and hence this didn't work for me, my bad.You really need to use search and also look back in the pages to find if others have had a similar problem and found a solution.
This is posted many times before...
It's the persistent file that is stored in your save game folder, which I can bet you copied over from your last game version.
To fix it...
DELETE the persistent file in these two folders (Save & AppData).
Try to start the game again.
Save folder... (Holiday Island/game/saves)
AppData folder... (C: user/***/AppData/roaming/RenPy/Island-1499865023)*** your user id
