You need to delete (or if this is part of a working system, convert) the old file.
I use json which makes saving and loading simple
If you remove the old file, a new one will be started. From that point forward,
it will work ok. I also suggest that you add some sort of backup mechanism.
One more time I emphasize that you at least encrypt that passwords before saving
