Hello,
I know it's old news already but after trying everything mentioned before in this topic I'm still stuck. Must have done something wrong. I'm after Galvantula fight, Melia's bag thing etc. The sensei (Kenta?) at his house isn't talking to me. I love this game a lot, so I'll be grateful for all possible help!
Edit: I downloaded the full game and didn't think to look for a patch. Looks like everything is working now.
Cheers
