why doesn't my keyboard midi trigger halion?

I just finally had it working, then turned it off to take a break, and it’s not working again. now I KNOW it’s just some stupid setting somewhere.
trying to get keyboard to trigger halion. no lights nothing.

update - definitely the midi triggering by external keyboard depends on it’s mood - is there something I should know? last time it was working, all of a sudden the note kept playing even after I released it, and then after i got tired of jamming to that note i unplugged the usb midi cord, and it STILL kept playing until I turned of Halion, and NOW it midi does not work again. also I noticed couple of times if the midi usb is plugged in to the laptop, then halion does not load or takes forever to load
