Wow ok, that post made no sense looking back over it. My bad. You know when you download the Stage Expansion 2.0 file, it has the folder with all the .rels and the other brres file? I put the .brres into my common5.pac where's it supposed to be, now the game can't load. Is it because I'm trying to have the Flaming Blue CSS going as well, or does that not affect it?
