Do you have the RPG Maker plugin for Joiplay installed? Also, is your version up to date? If not, that might be what's doing it. You can download both from Joiplay's website.
I just updated everything I had and it's still the same, is there any plugin that could at least fix it?
There's a rpg maker plugin for Joiplay, I forgot where you can downloan it, so search it in youtube.
