Cubase as slave with MTC , problem

I have ableton and cubase in 2 different mac
I need to let cubase slave to ableton
Cubase as slave only accept MTC , not MIDI clock
Ableton only can create MIDI clock , not MTC
so I am using Horae to generate MTC signal to send to cubase
When Ableton (+ Horae ) send MTC signal to cubase
Cubase seems getting MTC signal, but it jumps to the last bar of project and stuck.

Also I have 2 audio interface in each mac
so if any other sync system such as wordclock or ADAT etc can be used for this sync mission
I want to know the way how to.

Please support !!

Sounds like the cubase project time is not within the range of the incoming timecode ?
