Did you install both JB hotfixes? One in the end of LanguageBreak, another is from NiLuJe.
Where did you get KUAL packages? I used ones in NiLuJe’s Snapshots thread:

You need KUAL (coplate). Try putting install.bin and hotfix.bin (both in KUAL coplate archive) at the same time in mrpackages, then do ;log mrpi.
