Relic Castle

To get to the point. My game being worked on is playing fine, so I copied the game to the desktop and changed the configuration for where to save the game to. Then, I created a new game and saved the file after I started. But when I go to open up the file again, I get the End of File reached errors.

I've tried deleting the save files, but every time I create a new one it gives me this error. I'm guessing it has to do with Poketch, but I have no idea why it would do this so any help is appreciated
