Cubase Chord Pads Not Firing/Triggering Sound/Instrument

Hi, I’m running windows 10 & Cubase 8.5 Pro.

Can NOT get the chord pads to trigger any of the instruments, no matter what I do, they used to work just fine.
Is this an issue with Windows 10 ? Or a bug with Cubase ?

Check out the attached photo, in triggering the A7 chord, nothing is coming through on the Perc Synth [Halion Sonic SE] which has record enabled as well as monitor.

Any suggestions ?
