Based off of my understanding of your post, we had the EXACT same issue.

After replacing everything twice, I gave up and made the claim that it was a programming problem.

In the end, it was.
I'm no programmer, so please bear with me.

I just asked our lead programmer and my friend Matt what he did to make the LEDbox work, and he said he changed "K on" to "K forward"

Hope it helps!
