Apparently the version is already 1.04. Although I don't remember updating...

That's good if you already have a patched version.
If you're willing to test, please try this patcher, select US version. (There will be error if you already have 1.04. It's ok.)

I hope it works, but if it does not, please post some feedback here:-)
