MaddyCraft 2.12 problems

[Lao]

Hello I am hoping someone can help me. noone on the comments under this mod is responding, i also sent the maker a private message. so far nothing. So my problem is getting this to work. I followed the directions to the letter, tried it in drox and myui, both wont work, so i tested slcustom to see if it was maddy itself, it works beautifly in slcustom. Unfortunatly im not willing to use slcustom I want drox or myui. so how does one get it to work in these?
thank you in advance for any help
