This should have fixed it. Tell me if it worked. If not I will take another look at it.

Oh yeah this happens when the save file was used somewhere else.
Easy fix:
1.Remove your save file from your save folder.
2.Then you need to start a new game and save it on file 3.
3.Afterwards close the game and then replace the newly created save file with your own.
I also needed to do that to be able to play your file to look at it and fix it.
