Hacking ROM Hack GBA Advance Pokemon Sprite Editor ERROR

[Paoluxio]

Hi,
I have a problem with Pokemon Ruby hacking, I'm making an hack just for fun with all my friends and our group's memes as references, for the creation of new Pokemons. I'm using Advanced Pokemon Sprite Editor and this shows up, even when I try save the exact same rom without changing sprites, also I don't want to change Editing Program because I'm more comfy with this tool, since I used it on my old pc.
ANY HELP PLS?
