Basically, my beyond ave's error is kind of like this one. I remember output log says "start:shopinfo ave2.regist"(or something like this) and then "receiver returns failure". Weird.
Furthermore, my plugin runs very well in ave, even when I'm using ave's omnimix. But in beyond ave, besides the problem mentioned above, many charts can't be loaded if I want play them, and their cover images and titles are all white when I'm using omnimix. However, when I'm not starting spice with omnimix, the game could load new charts and information, but still has the same e-amusement error.
