Can you post the error?

I'm sorry, but an uncaught exception occurred.
While running game code:
File "renpy/common/000statements.rpy", line 671, in execute_call_screen
store._return = renpy.call_screen(name, *args, **kwargs)
File "renpy/common/00action_control.rpy", line 131, in __call__
renpy.show_screen(self.screen, *self.args, **self.kwargs)

If I click Rollback, sometimes it seems to work, but the next click throws the exception again.
