rune factory data corrupted

i am already having problems with my r4. my rune factory rom saves and plays alright but when i go to load it, it says the data is corrupt and deletes it.
bad rom? what can i do?

First make sure you're running the latest firmware, you can find out more about that in the common issues thread.

yep, firmware is all updated

Try deleting the original save file before you play it, then play it again.
