External keyboard not sending midi to Cantabile

I’m a new Cantabile user - just installed version 4.0.4357. I have a MODX connected to my laptop via iConnectivity MIO Midi/USB interface. My input and output routings in Cantabile are correct. I get sound when playing the onboard Cantabile keyboards (Soundpaint and Modwave Native) but no sound and no midi is being sent from the MODX. MODX sends midi to Soundpaint and Modwave Native when these two VSTs are in stand-alone mode. I’m running Windows10.

This appears to be a common problem as recently posted by Bdo518. But I don’t understand the responses - like running Admin scripts and such. Is there a “simple” solution that a new user like me can understand?

I’m attaching a screenshot showing my routing. (As a new user, I can’t submit the other screenshot which shows MIO as my Midi Port in along with Onscreen Keyboard).

I emailed Brad yesterday with this problem.

Thanks, Tom
