Nuendo 11 midi input OK but not connecting to VST

I just upgraded from Cubase to Nuendo 11. My Midi inputs are OK but do not connect to any of my VST. Any suggestions how to fix this? Maybe preferences?

Looking forward to some genius help.

problem solved, compared to Cubase in Nuendo I do need to click the record enable button, or the Monitor button. As far as I know this is nowhere mentioned.

same on Cubase
