Not sure why I didn't respond to this, sorry. You've probably resolved things one way or another, but just to clarify again for anyone reading: No actual save files are transferred, DataCrystal is its own thing, a way of carrying over a few bits of data from the previous game. It sounds like you already understand that, just re-iterating for others. Hopefully you've figured it out by now, but if not, feel free to ask again and I'll try to get back faster than 9 months (Not sure what happened there, notification must have glitched.)
