Rings of Fate Freezes (Not Mog of Death)

I originally got the MoD screen, but a firmware update fixed that quickly (along with Ninja Destiny and such), but now I'm having another problem with Final Fantasy Crystal Chronicles: Rings of Fate.

When you go with Al to the old temple (not too far into the game, where it's raining and is basically a water temple) I can go down about 2 floors to the first flood switch. Then if I try to leave that room through the only door, the game freezes.
It goes completely black like it's changing rooms, but stays that way, and the music starts to loop and glitch.

I've tried to get around this room, or do things in a different order, but it keeps freezing.

Is anyone else having a similar problem?
And is there a fix?

 

What are you playing it on? I assume flashcart. Backup everything (copy all your files somewhere on your computer) on your card (MicroSD etc.), and reformat it. That should fix the freezing. If that doesn't work, tell me the brand of your card (MicroSD etc.).

 

I'm using a 2 gigabyte FireCard (NAND clone).
Formatting it worked like a charm. Thanks alot!
