Jack Router, wavelab, Cubase 9 y MIxbus problem

Hi, I’m using this combination of elements, Cubase Pro 9, jack router, Harrison Mixbus and Wavelab Pro9. I am sending the cubase audio to MIxBus via Jack, then the MixBus audio to Wavelab, also using Jack, but I am having many problems, the recording is not activated, a window appears saying there is an error in the VST audio configuration , Monitoring and recording are soon activated. This with Cubase elements 9 trial did not happen to me.
Have you had a similar problem? Any solution? Remember that I have disabled the function to release asio driver in the background, also when Cubase / Nuendo are playing.
Any ideas?.
