Oddsound mts-esp -full version ..anyone using it?

Is anyone using the full version of Oddsound mts-esp in renoise ?
I am awaiting the license for the demoperiod , but I have already installed it and two things that seem odd
1-Opening re-opening the gui gives a black screen (both vst2-3 versions )
2-The navigation tabs don’t work at all
Seriously considering buying this plugin but have to be sure it’s working ( also got in touch with developers )


After r-opening
