Hi, thanks for the purchase. I believe you need to refresh the "Included files" in the IDE.
I usually use battle animations from here: https://github.com/Klokinator/FE-Repo, or I extract them from ROM hacks and place the CGs in a separate room using dedicated objects.
As for adding a new class, I'm preparing a HUGE update for the coming weeks; it will include a full campaign and a comprehensive tutorial on every step of the process.
