You do not mention which MKK version you installed.
Did you get the MKK archive from this post?
https://www.mobileread.com/forums/sh...d.php?t=225030
From inside of that archive, did you use?
Update_mkk_20141129-k4-ALL_install.bin
Have you tried to start KUAL two or more times in a row?
(It sometimes fails to run the first time you try it.)
