yeah i know he made some changes. i thought you might wanna know about that but it seems you already do know about it.
btw. i tried converting that code in lite-c myself and i got those problems with jumping also. then i tried to implement only KH jumping into my project and i once again i got the problem.
so i think that it's not a coincidence that jumping isn't working to me and to you, it has to do with newer Acknex version or c-script & lite-c language difference
