TT Dynamic Range meter no longer working

I was using this free VST plug in for a while. Since I switch to C7, I can’t use it any longer. It looks like generic state of it but can’t be change.
Does anybody have suggestion?

Maybe is a VST 2.2 that is too old and no longer supported… Your C7 Mixer has some useful tools for that now…
Check if that plug-in is 2.5 or look for an updated version of it if any…
